Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a computer system, and deals more specifically with a method and system for distributing electronic documents into and from a printing apparatus&#39; electronic mailbox. 
   2. Description of the Related Art 
   In today&#39;s office environment a need exists to transfer files and documents from one individual to another individual or to multiple individuals. One of the most popular and easiest methods of transferring documents is via electronic mail (e-mail). In this scenario, the individual sends an electronic copy of the document by attaching it as a file to an e-mail message and then sending the message to the recipient(s) e-mail address. In general, an e-mail address is comprised of a user&#39;s identification and an e-mail server identification. For example, in the e-mail address johndoe@email.com. “johndoe” identifies the recipient or user and “email.com” identifies the e-mail server. When the e-mail arrives at the e-mail server, the e-mail message along with the attached electronic copy of the document are stored in a electronic virtual mailbox of the e-mail application, where the mailbox is identified by the user&#39;s identification part of the e-mail address. The electronic virtual mailbox is typically either a memory location or a disk storage area on the server. Other methods of transferring files and documents include using a file transfer protocol (FTP) application and a network terminal file system (NTFS) application. 
   In many instances, in addition to an electronic copy of the document, a hardcopy of the document is required as well. One method of obtaining a hardcopy involves the use of a printing apparatus, such as a digital copier. In a typical case, to obtain a hardcopy of the electronic document, the document recipient opens the document using its associated application, and then prints the document on the digital copier using the application&#39;s print function. In another instance, the document sender wants the document recipient to have a “print-ready” copy of the document. In this case, the document sender makes use of the digital copier&#39;s electronic mailbox feature. Most digital copiers contain electronic mailboxes, where an electronic mailbox is assigned to a particular user of that digital copier. It works in much the same manner as the e-mail electronic virtual mailbox. However, instead of e-mailing the document to the digital copier, the document sender prints the document to the document recipient&#39;s electronic mailbox residing on the digital copier. 
   The current approach of providing the document recipient with an electronic copy of the document via e-mail and a “print-ready” copy requires two separate actions on the part of the document sender. The document sender must go through the steps of e-mailing a copy of the document to the document recipient, as well as go through the steps of storing a “print-ready” copy on the digital copier. These separate actions are necessary because there is no connectivity between the document recipient&#39;s e-mail electronic virtual mailbox and the document recipient&#39;s digital copier electronic mailbox. 
   In addition, in order to send a document to the document recipient&#39;s digital copier electronic mailbox, the document sender must have knowledge of the identification format used to identify the document recipient&#39;s electronic mailbox on the digital copier. This identification format is typically not user friendly (i.e., mailboxes are identified by numbers not users and the association between numbers and users is not readily available). 
   Another problem is that the assignment of users to digital copier electronic mailboxes can vary from digital copier to digital copier. For example, in a company with two digital copiers, an employee could be assigned electronic mailbox “1” on the first digital copier and electronic mailbox “2” on the second digital copier. Or, an employee may only be assigned an electronic mailbox on only one of the digital copiers. Under either scenario, a co-worker wanting to provide a “print-ready” copy of a document to the employee&#39;s digital copier electronic mailbox would have to know which digital copier or copiers the employee was assigned to and what the employee&#39;s electronic mailbox number was on each digital copier. In order to provide any future documents, the co-worker would have to keep track of this information. The same problems apply when trying to provide an electronic copy of the document via other electronic document transfer applications (e.g. FTP). 
   What is needed is an application that simplifies the process for providing recipients with an electronic copy of a document via an electronic document transfer application and a “print-ready” copy of the document via a printing apparatus. 
   SUMMARY OF THE INVENTION 
   It is an object of the foregoing invention to address the foregoing difficulty by providing an application that simplifies the process for providing recipients with an electronic copy of a document via an electronic document transfer application and a “print-ready” copy via a printing apparatus. 
   Thus one aspect of the present invention is method for distributing electronic documents to at least one storage location of an electronic document transfer application and to at least one electronic mailbox residing on at least one printing apparatus. A client application executes to transmit the electronic documents, while a complimentary server application functions to receive the electronic documents from the client application. The server application associates the at least one storage location of the electronic document transfer application with the at least one electronic mailbox residing on the at least one printing apparatus and transmits the electronic documents to the at least one electronic mailbox residing on the least one printing apparatus based on the association. In addition, an electronic document transfer application functions to receive the electronic documents from either the client application or the server application. The electronic addresses corresponding to the at least one storage location of the electronic document transfer application are the same as the electronic addresses corresponding to the at least one electronic mailbox residing on the at least one printing apparatus. 
   In yet another aspect, the at least one printing apparatus includes a scanning function, where the client application initiates the scanning operation. The results of the scanning operation are stored in at least one electronic mailbox residing on the printing apparatus and transmitted to the electronic document transfer application. 
   In still yet another aspect, retrieval of an electronic document is attempted from an electronic mailbox residing on a first printing apparatus. If the electronic mailbox from which the retrieval is attempted does not reside on the first printing apparatus, the electronic document is retrieved from a second printing apparatus, where the electronic document is transmitted from the second printing apparatus to the first printing apparatus. 
   This brief summary has been provided so that the nature of the invention may be understood quickly. A more complete understanding of the invention can be obtained by reference to the following detailed description of the preferred embodiment(s) thereof in connection with the attached drawings.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The preferred embodiment of the present invention comprises a plurality of client computers and a plurality of printing apparatuses. In order to simplify the following description, reference will be made to only one client computer and two printing apparatuses, where the printing apparatuses are digital copiers. This should not be seen in anyway to limit the scope of the present invention. In addition, an e-mail application will be used as the electronic document transfer application in the description of the present invention. Any electronic transfer document application, such as FTP or NTFS enabling practice of the present is applicable. 
     FIG. 1  is a representational view depicting a general configuration of the system of the present invention. Document distribution system  1  includes e-mail server computer  5 , server computer  9 , digital copier  11 , digital copier  20 , and client computers  2 ,  4 . Client computers  2 ,  4  are connected to e-mail server computer  5  and server computer  9  via a network interface  14 ,  15 ,  16 , and  17 . E-mail server computer  5  and server computer  9  are connected via network interface  18 . Server computer  9  is connected to digital copier  11  via network interface  19  and digital copier  20  via network interface  23 . 
   E-mail server contains e-mail application  6 , such as Microsoft® Outlook®. E-mail application includes a plurality of electronic virtual mailboxes  7 ,  8 . Server computer  9  contains server application, hereinafter referred to as multiple mailbox management application  10 , of the present invention.

Digital copier  11  includes a plurality of electronic mailboxes  12 ,  13  and digital copier  20  includes a plurality of electronic mailboxes  21 ,  22 . 
     FIG. 2  is a block diagram of the internal architecture of client computer  2  and  4 . Shown in  FIG. 2  is CPU  20 , which is preferably a Pentium-type microprocessor, interface to computer bus  21 . Also interface to computer bus  21  are printer interface  22 , to allow client computer  4 ,  8  to communicate with a local printer (not shown), network interface  23  to enable communications between client computer  2 ,  4  and a network, modem interface  26  to enable communications between client computer  4 ,  8  and its internal modem (not shown), display interface  27  for interfacing with a display monitor (not shown), keyboard interface  30  for interfacing with a keyboard (not shown), and mouse interface  29  for interfacing with a mouse (not shown). Of course, if client computer  4 ,  8  connects to the World Wide Web  12  by a connection other than a telephone connection, a suitable interface other than modem interface  26  by be utilized. 
   Read only memory (ROM)  31  stores invariant computer-executable process steps for basic system functions such as basic I/O, start-up, or reception of keystrokes from a keyboard. Main random access memory (RAM)  32  provides CPU  20  with memory storage that can be accessed quickly. In this regard, computer-executable process steps of the document distributor application of the present invention or other applications are transferred from disk  3  over computer bus  21  to RAM  32  and executed therefrom by CPU  20 . 
   Also shown in  FIG. 2  is disk  3 , which, in addition to the application of the present invention, includes a windowing operating system, a web browser executable on the particular windowing operating system, other applications which may include word processing, spreadsheet, graphics, and gaming applications. Disk  3  further includes data files and device drivers as shown. 
     FIG. 3  is a flowchart describing the preferred embodiment for configuring multiple mailbox management  10  of the present invention. Briefly, multiple mailbox application  10  is configured to associate electronic virtual mailboxes  7 ,  8  of e-mail application  6  with electronic mailboxes  12 ,  13  residing on digital copier  11 . Part of this association includes ensuring that the electronic addresses of e-mail application&#39;s  6  electronic virtual mailboxes  7 ,  8  are the same as the electronic addresses of digital copier&#39;s  11  electronic mailboxes  12 ,  13 . Configuration of multiple mailbox application  10  also includes establishing a “guest” electronic mailbox, hereinafter referred to as a guest account, on digital copier  11  to enable a user to retrieve a document when the user has not been assigned an electronic mailbox  12 ,  13  on digital copier  11 . 
   In more detail, multiple mailbox application  10  is initiated in step S 3 - 1 . In step S 3 - 2 , a list of current e-mail application  6  users is obtained. A check is then made in step S 3 - 3  whether multiple mailbox application  10  had previously been invoked. If multiple mailbox application  10  had previously been invoked, flow proceeds to step S 3 - 4 , where a determination is made whether any e-mail application  6  users have been deleted since the last time multiple mailbox application  10  was run. If no users were deleted, flow proceeds to step S 3 - 7  described below. If any users were deleted, than the current e-mail application mailbox to digital copier mailbox association, which is described in more detail below, is retrieved in step S 3 - 5 . The association for deleted users is removed in step S 3 - 6 . 
   Flow then proceeds to step S 3 - 7 , where a check is made to determine whether any e-mail application  6  users were added since the last time multiple mailbox application  10  was run. If no users were added, flow proceeds to step S 3 - 12  described below. If any users were added, in step S 3 - 8 , the digital copiers to add electronic mailboxes for the new user(s) are chosen. Preferably, each user is assigned an electronic mailbox in each available digital copier. For example, in the system of  FIG. 1 , each user would be assigned an electronic mailbox in digital copier  11  and digital copier  20 . In addition, the same electronic address used to define the electronic mailbox in digital copier  11  would be used to define the electronic mailbox in digital copier  20 . This is done so a document sender does not have to remember which digital copier(s) a document recipient is assigned to and what the document recipient&#39;s address is for a particular digital copier. 
   Returning to the flow of  FIG. 3 , in step S 3 - 9 , the chosen digital copier(s) are checked to ensure there are enough spare electronic mailboxes to accommodate the new user(s). If there are not enough spare electronic mailboxes on a particular digital copier, a different one must be chosen in step S 3 - 8 . If enough spare electronic mailboxes exist on a particular digital copier, then in step S 3 - 10 , the new user(s) are assigned an electronic mailbox on that digital copier. Once all the new users have been assigned respective electronic mailboxes, e-mail application electronic virtual mailbox to digital copier mailbox association, as described below, is updated and saved in step S 3 - 11 . Flow proceeds to step S 3 - 12 , where verification is performed to ensure that multiple mailbox application  10  did not disable any of the digital copiers. From there, multiple mailbox application  10  is ready to accept new input (step S 3 - 22 ). 
   If, in step S 3 - 3 , the determination is that multiple mailbox application  10  is being invoked for the first time, flow proceeds to step S 3 - 13 . Step S 3 - 13  verifies whether e-mail application&#39;s  6  electronic virtual mailboxes  7 ,  8  have been associated with digital copier&#39;s  11  electronic mailboxes  12 ,  13 . This step is performed for all available digital copiers. If they have been associated, in step S 3 - 14  verification is performed to ensure that multiple mailbox application  10  did not disable any of the digital copiers. 
   Flow proceeds to step S 3 - 15  in the event that one or more of e-mail application&#39;s  6  electronic virtual mailboxes  7 ,  8  have not been associated with digital copier&#39;s  11  electronic mailboxes  12 ,  13 . This would also be the case if no association existed with respect to any other available digital copier. In step S 3 - 15 , multiple mailbox application  10  obtains information and mailbox capabilities from digital copier  11 . This includes data such as network information, digital copier&#39;s user-friendly name, and number of electronic virtual mailboxes. Once this information is obtained, in step S 3 - 16 , a decision is made whether to allow a user assigned an electronic mailbox one (i.e., digital copier  11 ) and not one on another digital copier (i.e., digital copier  20 ) access to a guest account on digital copier  11 . 
   If access to a guest account is desired, in step S 3 - 17 , at least one electronic mailbox on digital copier  11  is reserved for a guest account. Typical digital copiers contain up to 100 electronic mailboxes. Preferably, 99 would be reserved for assigned users and one reserved as the guest account. However, any combination of assigned users and guest accounts that would enable practice of the present invention would be applicable. If access to a guest account is not desired, or after a guest account has been created, flow proceeds to step S 3 - 18 . 
   In step S 3 - 18 , any e-mail application  6  electronic virtual mailboxes  7 ,  8  not associated with any digital copier  11  electronic mailboxes  12 ,  13 , are associated. This association step includes assigning the electronic mailbox  12  on digital copier  11  the same electronic addresses as that of the corresponding e-mail application  6  electronic virtual mailbox  7 . Upon completion of the association in step S 3 - 18 , in step S 3 - 19 , digital copier  11  is assigned the electronic mailboxes. In the preferred embodiment, the assignment is done on a logical user group basis. In other words, rather than update digital copier  11  on a user-by-user basis, digital copier  11  is updated using a logical user group. For example, if digital copier  11  is located in a particular area of an office environment, all users within the same area are placed into a single logical user group that would be used to update digital copier&#39;s  11  electronic virtual mailboxes. Under this embodiment, if multiple user changes occur at the same time, digital copier  11  would only have to be updated once. Updating digital copier  11  manually is not precluded by this embodiment. 
   Following step S 3 - 19 , in step S 3 - 20 , the e-mail application electronic virtual mailbox to digital copier electronic mailbox association is updated and saved. In step S 3 - 21 , verification is performed to ensure that multiple mailbox application  10  has not disabled any of the digital copiers. From there, multiple mailbox application  10  is ready to receive new input (step S 3 - 22 ). 
     FIG. 4  is a flowchart describing the preferred embodiment for configuring the document distributor application of the present invention. Briefly, document distributor application  3  is configured to allow a user at client computer  1  to provide a recipient with an electronic copy of a document as well as a “print-ready” copy of the document at a digital copier. 
   More specifically, in step S 4 - 1 , document distributor application  3  is initiated. In step S 4 - 2 , document distributor application  3  attempts to locate the server running multiple mailbox application  10 . If, in step S 4 - 3 , document distributor application  3  did not automatically locate server  9 , the user is prompted to browse for a server running multiple mailbox application  10  in step S 4 - 4 . If in step S 4 - 5  no server is found, an error is returned to the user in step S 4 - 6 . 
   If, in step S 4 - 3  server  9  is found or if the user finds server  9  in step S 4 - 5 , flow proceeds to step S 4 - 7 . In step S 4 - 7 , the user determines whether to provide a recipient with only “print-ready” copies of an electronic document or both a “print-ready” copy and an electronic copy. Flow then proceeds either to step S 4 - 8  (“print-ready ” and electronic copy) or step S 4 - 9  (“print-ready” only), and then to step S 4 - 10 , where document distributor application  3  is ready to receive input. 
     FIG. 5  is a flowchart describing providing an electronic document according to the present invention. Briefly, a user on client computer  2  invokes document distributor application  3  from the application associated with the electronic document to be transmitted. The user is provided with options where to transmit the electronic document, including digital copier  11 . Upon receipt of the document by digital copier  11 , digital copier  11  determines whether the recipient has been assigned an electronic mailbox  12  and whether there is enough memory in the electronic mailbox  12  to store the document. 
   The detailed description of  FIG. 5  is provided with respect to document distributor application  3  running in a Microsoft® Windows operating system environment. However, document distributor application  3  is not limited to this environment and any Microsoft® Windows operating system specific references are meant for illustrative purposes only. In more detail, in step S 5 - 1 , the electronic document is opened in its native application, i.e., Microsoft® Word. In step S 5 - 2 , the user initiates document distributor application  3  from the native application. For example, in Microsoft® Word, the “File” option is chosen from the Word toolbar, followed by selection of the “Send To” option in the ensuing drop-down menu. Within the “Send To” menu, the user would select the option associated with document distributor application  3 . 
   In step S 5 - 3 , the user is provided with user interface  6 - 1  of  FIG. 6 . User interface  6 - 1  contains two sections, Printer section  6 - 2  and Mail To section  6 - 6 . Printer section  6 - 2  contains, among other things, “Name” field  6 - 3 , “Print to Mailbox” field  64 , and “Distribute to Mailbox” field  6 - 5 . All three fields preferably default to an unselected state. In the preferred embodiment, if no digital copier is selected in “Name” field  6 - 5 , when the electronic document is transmitted to the digital copier as described below, the electronic document is transmitted to the appropriate electronic mailbox on each digital copier where that electronic mailbox exists. In another embodiment, the user can transmit the electronic document to only a specific digital copier by selecting the digital copier in “Name” field  6 - 3 . Mail To section  6 - 6  contains, among other things, “Recipients” field  6 - 7  and “Subject” field  6 - 8 . These two fields default to the unselected state as well. 
   Returning to the flow of  FIG. 5 , in step S 5 - 4  the user determines which type of mailbox operation to invoke. If “Distribute to Mailbox” option  6 - 5  is chosen, user interface changes to user interface  7 - 1  of  FIG. 7 . User interface  7 - 1  is similar to user interface  6 - 1 , except that “Distribute to Mailbox” field  7 - 3  is checked, and that “Recipients” field  7 - 4  and “Subject” field  7 - 5  are unlocked and data can be entered in these fields. In step S 5 - 7  the user selects the recipients to whom the electronic document is to be sent in “Recipients” field  74  and enters the subject of the document in “Subject” field  7 - 5 . User interface  7 - 1  illustrates selection of a specific digital copier in “Name” field  7 - 2 . 
   If “Print to Mailbox” field  64  is chosen, user interface  6 - 1  changes to user interface  8 - 1  of  FIG. 8 . User interface  8 - 1  is similar to user interface  7 - 1 , except that “Print to Mailbox” field  8 - 3  is checked and “Subject” field  84  is unlocked and data can be entered in this field. Because the only recipient under this option is the user, “Recipients” field  8 - 5  remains grayed-out. In step S 5 - 6 , the user enters the subject of the document in “Subject” field  84 . User interface  8 - 1  also illustrates selection of a specific printer. 
   After the user has chosen the mailbox operation and entered the appropriate information on the appropriate user interface, flow proceeds to step S 5 - 8  where the document is rendered by the selected digital copier&#39;s associate device driver located on client computer  2 . In step S 5 - 12 , the rendered document is transmitted to multiple mailbox application  10  residing on server computer  9 . The transmitted data includes the document, as well as the recipient(s)&#39; user information, which corresponds to the recipient(s)&#39; e-mail application  6  electronic virtual mailbox  7 . 
   In step S 5 - 9 , if document distributor application  3  was configured in step S 4 - 7  to provide both a “print-ready” copy and an electronic copy of the electronic document, an electronic copy of the electronic document is attached as a file to an e-mail message in step S 5 - 9  and in step S 5 - 10 , the e-mail message and attached file would be sent to the recipient&#39;s e-mail application  6  electronic virtual mailbox  7 . 
   In step  5 - 13 , after receiving the rendered document from document distributor application  3 , multiple management application  10  verifies that recipient(s)&#39; user information is associated with a digital copier&#39;s electronic mailbox  12 . If, in step S 5 - 14  it is determined no association exists, an error is recorded on server  9  and sent to the user in step S 5 - 15 . If, in step S 5 - 14 , it is determined an associated exists, in step S 5 - 16 , multiple mailbox application  10  preferably attempts to transmit the rendered document to the appropriate electronic mailbox on all the available digital copiers where that electronic mailbox resides. In another embodiment, the rendered document is transmitted to the appropriate electronic mailbox on a specified digital copier as illustrated in “Name” field  7 - 2 ,  8 - 2 . 
   A check is performed in step S 5 - 17  ensure there is enough memory in each electronic mailbox to store the rendered document. For those electronic mailboxes with enough memory, the rendered document is stored at that location, per step S 5 - 19 . Flow then proceeds to step S 5 - 20 , where the document is ready to be retrieved. If a particular electronic mailbox does not have enough memory, in step S 5 - 18 , an error is recorded on server  9  and the user is presented with an error and an option to either delete documents from the mailbox or temporarily store the document on server  9 . 
     FIG. 9  is a flowchart describing retrieving a hardcopy of an electronic document according to the present invention. Briefly, of the steps depicted in  FIG. 9  associated with retrieving a document from a user&#39;s digital copier&#39;s electronic mailbox, steps S 9 - 1 , S 9 - 2 , S 9 - 3 , S 9 - 4  (“yes” branch), S 9 - 13 , S 9 - 14 , S 9 - 15 , and S 9 - 16  are consistent with the current state of the art. Since they are not part of the present invention, they are only being included to provide a complete picture of the environment in which the present invention operates. No detailed discussion associated with these steps is being provided. 
   The present invention&#39;s feature begins when the determination is made in step S 9 - 4  that the user attempting to access digital copier  11  does not have a valid electronic mailbox  13  on the digital copier  11 . In step S 9 - 6 , a check is made whether a guest account was created on digital copier  11 . If no guest account was established, in step S 9 - 5 , an error is recorded on server  9  and the user is notified of the error via digital copier&#39;s  11  user interface. 
   Flow proceeds to step S 9 - 7  in the event that a guest account has been established on digital copier  11 . In step S 9 - 7 , digital copier  11  transmits to multiple mailbox application  10 , user information entered when the user attempted to retrieve a document. This information can include the user&#39;s electronic mailbox information. Upon receiving the information, in step S 9 - 8 , multiple mailbox application  10  verifies whether the user has an associated electronic mailbox on any other digital copier. If the user does not, in steps S 9 - 9 , an error is recorded on server  9  and the user is notified of the error via digital copier&#39;s  11  user interface. 
   If it is determined that the user has an electronic mailbox on another digital copier (i.e., digital copier  20 ), in step S 9 - 10 , multiple mailbox application  10  locates digital copier  20 . Digital copier  20  is located via the association between e-mail application electronic virtual mailboxes and digital copier electronic mailboxes. Returning to the flow of  FIG. 9 , in step S 9 - 11 , multiple mailbox application  10  instructs the digital copier  20  to transmit the contents of the user&#39;s electronic mailbox to the guest account on digital copier  11 . 
   The other steps of  FIG. 9  related to the present invention are steps S 9 - 16  through S 9 - 18 . In step S 9 - 16 , a check is made whether the document was retrieved from a guest account. In the event it was, flow proceeds to step S 9 - 17 , where the guest account is deleted after the document is retrieved. After the guest account is deleted, or if the document was not retrieved from a guest account, in step S 9 - 18 , digital copier  11  is ready for another mailbox to be accessed, 
     FIG. 10  is a flowchart describing scanning a document using document distributor application  3  of the present invention. Briefly, using document distributor application  3 , a user is able to scan a document at digital copier  11  from client computer  2  via multiple mailbox application  10 . 
   In more detail, in step S 10 - 1 , a user initiates document distributor application  3 . For example, in a Microsoft® 0  Windows operating system environment, a user double clicks on document distributor application  3  icon in the Windows desktop. In step S 10 - 2 , document distributor application  3  determines it was initiated outside of an application (i.e., Microsoft® Word), and provides user interface  11 - 1  as depicted in  FIG. 10 . 
   User interface  11 - 1  is divided into two sections. Scanner section  11 - 2  contains “Name” field  11 - 3 , “Scan Now” button  114 , and “Load from Mailbox” field  11 - 5 . Mail To Section  11 - 6  contains “Mail to myself” field  11 - 7 , “Subject” field  11 - 8 , and “Recipients” field  11 - 9 . Preferably, “Load from Mailbox” field  11 - 4  and “Mail to myself” field  11 - 7  default to the checked state. 
   Returning to the flow of  FIG. 10 , in step S 10 - 3 , the user selects the digital copier the user is going to scan the document from by filling in the digital copier name in “Name” field  10 - 2 . The name can either be typed in or selected from a drop-down menu. After the digital copier is selected, in step S 10 - 4  verification of whether the user has a valid electronic mailbox on the selected digital copier is performed. If this verification fails, a check is performed in step S 10 - 5  to determine whether the digital copier has been allocated a guest account. If no guest account exits, an error notification is sent to server  9  and to client computer  2  in step S 10 - 6 . 
   If a guest account exits, flow proceeds to step S 10 - 7 , where it is determined whether the user has an electronic mailbox on a different digital copier than the one selected in “Name” field  11 - 3 . If the user does not, an error is recorded on server  9  and an error notification is sent to client computer  2  in step S 10 - 8 . If the user does have an electronic mailbox on a different digital copier, in step S 10 - 9 , multiple mailbox application  10  locates another digital copier where the user has an electronic mailbox. This is accomplished using the association between e-mail application electronic virtual mailboxes and digital copier electronic mailboxes described above. 
   Next, in step S 10 - 10 , multiple mailbox application  10  provides notification to document distributor application  3  on client computer  2  that user does not have a valid electronic mailbox on the selected digital copier. In step S 10 - 11 , the user is presented with an option of having the scanned document delivered either to the guest account on the selected digital copier or to the user&#39;s electronic mailbox on a different digital copier. 
   If the user chooses to use the guest account on the selected digital copier, flow proceeds to step S 10 - 12 . Returning to step S 10 - 4 , if the user has a valid electronic mailbox on the selected digital copier, flow also proceeds to step S 10 - 12 . In step S 10 - 12 , the user verifies that “Load from Mailbox” field  114  is unchecked, and if not, unchecks it. Next, in step S 10 - 13 , the document to be scanned is placed on the scan tray of the selected digital copier. Flow then proceeds to step S 10 - 16 , which is described below. 
   Returning to step S 10 - 11 , if the user chooses to use the user&#39;s electronic mailbox on a digital copier different than the selected digital copier, the user next verifies that “Load from Mailbox” field  11 - 4  is unchecked, and if not, unchecks it. (step  10 - 14 ). Then, in step S 10 - 15 , the document to be scanned is placed on the scan tray of the different digital copier. Flow then proceeds to step S 10 - 16 , which is described below. 
   In step S 10 - 16 , “Mail to myself” field  11 - 7  is either left in the checked state or placed in the unchecked state depending on who the recipient of the scan operation is. If “Mail to myself” field  11 - 7  is left checked, the user is the only recipient of the scan operation, and in step S 10 - 17 , the user need only verify the digital copier in “Name” field  11 - 3  is where the scan operation is to be performed, and to provide a title for the scanned document in “Subject” field  11 - 8 . Next, in step S 10 - 19 , “Scan Now” button  11 - 4  is selected to initiate the scan operation. 
   If, in step S 10 - 16 , “Mail to myself” field  11 - 7  is placed in the un-checked state, user interface  11 - 1  changes to user interface  12 - 1  of  FIG. 12 . User interface  12 - 1  is similar to user interface  11 - 1 , except that “Recipients” field  12 - 9  becomes active. Per step S 10 - 18 , the user can enter multiple recipients in “Recipients” field  12 - 9 . As in user interface  11 - 1 , the user also verifies the digital copier in “Name” field  12 - 3  and provides a title for the scanned document in “Subject” field  12 - 8 . Next in step S 10 - 19 , “Scan Now” button  12 - 4  is selected to initiate the scan operation. 
   Upon selection of “Scan Now” button  11 - 4 ,  12 - 4 , in step S 10 - 20  document distributor application  3  transmits client computer  2  authentication information to multiple mailbox application  10 . Multiple mailbox application  10  in turn transmits the authentication information to the selected digital copier to authenticate the user on the selected digital copier. Following authentication of the user, the digital copier in step S 10 - 21  performs the following: scans the document into the recipient&#39;s electronic mailbox on the digital copier where the scan operation occurred, provides an electronic copy of the scanned document to the recipients, and, via multiple mailbox application  10 , provides a copy of the document to every one of user&#39;s electronic mailbox on every available digital copier. Multiple mailbox application  10  preferably performs the last function by locating, using the association between e-mail application electronic virtual mailboxes and digital copier electronic mailboxes, any other digital copiers where the user has an electronic mailbox, and transmitting a copy of the document to the user&#39; electronic mailbox on the located digital copiers. If in step S 10 - 22 , the scanned document was stored in the guest account, then in step S 10 - 23 , the guest account is cleared. After clearing the guest account, or if in step S 10 - 23  the scanned document was not stored in the guest account, the digital copier and document distributor application  3  are ready to receive new input (step S 10 - 24 ). 
     FIG. 13  is a flowchart describing transmitting a previously scanned document using document distributor application  3  of the present invention. Briefly, document distributor application  3  allows a user to access a previously scanned document from a digital copier&#39;s electronic mailbox and transmit an electronic copy of the document. 
   In step S 13 - 1 , a user initiates document distributor application  3  in the same manner as described above with respect to step S 10 - 1 . In step S 13 - 2 , document distributor application determines it was initiated outside of an application (i.e., Microsoft® Word), and provides user interface  14 - 1  as shown in  FIG. 14 . User interface  14 - 1  is identical in format to that of user interfaces  11 - 1  and  12 - 1 . 
   Next, in step S 13 - 3 , the user selects the digital copier containing the electronic mailbox the user would like to access by filling in the digital copier name in “Name” field  14 - 3 . The name can either by typed in or selected from a drop-down menu. After the digital copier is selected, in step S 13 - 4 , verification of whether the user has a valid mailbox on the selected digital copier is performed. If the verification fails, a check is performed in step S 13 - 5  to determine whether the user has an electronic mailbox on a different digital copier. If the user does not, in step S 13 - 6 , an error is recorded on server  9  and an error notification is provided to client computer  2 . 
   If the user has an electronic mailbox on a digital copier other than the selected digital copier, flow proceeds to step S 13 - 7 . Multiple mailbox application  10  locates any other digital copiers where the user has an electronic mailbox. This is accomplished by using the association between e-mail application electronic virtual mailboxes and digital copier electronic mailboxes described above. In step S 13 - 8 , multiple mailbox application  10  provides the user with a list of the digital copiers where the user has an electronic mailbox. Based on this list, the user selects a new digital copier in “Names” field  14 - 2 . 
   Returning to step S 13 - 4 , if the user has an electronic mailbox on the digital copier that was selected in steps S 13 - 3  or S 13 - 9 , flow proceeds to step S 13 - 10 . In step S 13 - 10 , if “Load to Mailbox” field  14 - 5  is not checked, then the user checks it. Then, in steps S 13 - 11  and S 13 - 12 , the user selects the electronic mailbox and document in “Document” field  14 - 4 . 
   In step S 13 - 13 , “Mail to myself” field  14 - 7  is either checked or un-checked. If “Mail to myself” field  14 - 7  is checked, the user is the only recipient of the electronic document, and “Recipients” field  14 - 9  remains grayed-out. In step S 13 - 14 , the user need only provide a title for the document in “Subject” field  14 - 8 . If “Mail to myself” field  14 - 7  is not checked, user interface  14 - 1  changes to user interface  15 - 1  of  FIG. 15 . User interface  15 - 1  is similar to user interface  14 - 1 , except that “Recipients” field  15 - 2  becomes active. Per step S 13 - 15 , the user can enter multiple recipients in “Recipients” field  15 - 9 . As in user interface  14 - 1 , the user also provides a title for the electronic document in “Subject” field  15 - 8 . 
   Following steps S 13 - 14  or S 13 - 15 , in step S 13 - 16 , the user selects “OK” button  14 - 6 ,  15 - 4  to initiate the transmission operation. Upon selection of “OK” button, document distributor application  3  transmits client computer authentication information to multiple mailbox application  10  in step S 13 - 16 . Multiple mailbox application  10  in turn transmits the authentication information to the selected digital copier to authenticate the user on the digital copier. Following authentication of the user, in step S 13 - 18 , the digital copier provides an electronic copy of the electronic document as well as a “print-ready” copy to the recipients in “Recipients” field  15 - 9 . In the case of  FIG. 14 , where the user is the only recipient, the digital copier only provides an electronic copy of the electronic document. Digital copier and document distributor application  3  are then ready to receive new input (step S 13 - 18 ). 
   The above embodiment of the present invention includes e-mail application  6  for transmitting an electronic copy of an electronic document. In another embodiment, an FTP application can be substituted for e-mail application  6 , where the FTP application would function to transmit an electronic copy of an electronic document. In this embodiment, the FTP application includes the same electronic address storage location feature as e-mail application  6 . The nomenclature for the electronic address storage location in FTP application is different than that in e-mail application  6 , but the functionality is the same. As such, in this embodiment, at least one FTP application electronic storage function is associated with at least one electronic mailbox residing on at least one printing apparatus. 
   In yet another embodiment, an NTFS application can be substituted for e-mail application  6 , where the NTFS application would function to transmit an electronic copy of an electronic document. In this embodiment, the NTFS application includes the same electronic address storage location feature as e-mail application  6 . The nomenclature for the electronic address storage location in NTFS application is different, but the functionality is the same. As such, in this embodiment, at least one NTFS application electronic storage location is associated with at least one electronic mailbox residing on at least one printing apparatus.
