     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Preferred exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings.  
       FIG. 1  is a block diagram illustrating the functional configuration of a printer  10  according to an embodiment of the present invention.  
      The printer  10  comprises a network interface (I/F)  101  that controls interfacing with the network, a manual control section  102  that performs control relating to, for example, input of various types of information and issue of various types of command, a display  103  that displays various types of information, an image processing section  104  that performs image processing in which printing data is generated from image information of a printable object, an image forming section  105  that forms an image on a recording medium corresponding to printing data generated by image processing by the image processing section  104 , a storage section  106  that stores various types of information such as an operating program, consumables sales information storage section  107 , an external interface (I/F) section  108  that controls interfacing with external equipment such as a dedicated tool  17 , to be described, an updating processing section  109  that performs updating processing of the consumables sales information stored in the consumables sales information storage section  107 , a consumption detection section  110  that detects the state of consumption of the various types of consumables used in the printer  10 , and a control section  111  that performs control of this entire printer.  
      As consumables that are consumed by the image printing and by the image forming section  105 , the printer  10  employs, for example, a toner cartridge, a photosensitive drum unit and recording paper.  
      The consumables sales information storage section  107  stores consumables sales information (D 1 ) relating to sale of various types of consumables consumed by the printing operation of the printer  10 .  
      The consumables sales information storage section  107  comprises a non-volatile memory such as a flash ROM, EEPROM or HardDisk in which information can be rewritten.  
      The control section  111  reads consumables sales information from the consumables sales information storage section  107  in response to a prescribed printing start-up command, such as a printing command corresponding to a prescribed control action at the manual control section  102  and controls the image forming section  105  to deliver printed output onto the recording medium by image processing by performed the image processing section  104 .  
      In the printer  10 , the consumables sales information stored in the consumables sales information section  107  is information relating to the sales details of consumables used by the printer  10  such as the name of the shop, address, contact details, i.e., telephone number, fax (facsimile device) number, e-mail address, homepage address (Web address) of the seller that sells the printer  10 , the name of the consumables, the name of the type of printer, the corresponding consumables model number, the cost, information as to the remaining amount of the consumables, and sales promotion information such as advertising information for promoting consumables sales by this seller.  
      The consumables sales information comprising the above information items is stored in the consumables sales information storage section  107  of the printer  10  by this manufacturer when the manufacturer manufactures and ships the printer  10 .  
      The printer  10  in which the consumables sales information has been stored in the consumables sales information storage section  107  by the manufacturer is then sold to the user through the seller.  
      In this case, the consumables sales information stored in the consumables sales information storage section  107  of the printer  10  when shipped by the manufacturer is information relating to the sale of consumables by the seller who sold the printer  10  under a commission from the manufacturer, for example.  
      That is, the information as to the shop name, address and contact details in the consumables sales information stored in the consumables sales information storage section  107  consists of the various items of information of the seller who sold the printer  10 .  
      In the printer  10 , the consumables sales information stored in the consumables sales information storage section  107  is printed out onto a recording medium under control exercised by the control section  111  described above.  
      In this case, depending on the layout of the consumables sales information that is to be printed, for example, the shop name, address, contact details, consumables name, and advertising information of this seller who sold the printer  10  are printed on the recording medium.  
      By referring to the contact details information printed on the storage medium, the user can communicate with this seller and can place an order with the seller, by selecting the desired consumables in reference to the information such as the consumables name that is printed together therewith.  
      As mentioned above, the printed contact details information is information as to the contact details of the seller&#39;s shop where the printer  10  was sold.  
      It is therefore very convenient for the user of the printer  10  to place an order for the consumables of the printer  10  with the seller where the printer  10  was purchased, by using this contact details information.  
      On the other hand, the seller is able to induce users to select the seller&#39;s company as one of the possible sources for ordering consumables through the consumables ordering operation by the user who purchased the printer  10  from the seller&#39;s company based on the printout of consumables sales information as described above, whereby the seller&#39;s competitiveness in regard to other sellers can be improved.  
      In order to store the consumables sales information in the consumables sales information storage section  107  of the printer  10  according to present invention, the methods shown in  FIG. 2  and  FIG. 3  may be adopted.  
       FIG. 2  shows an example of operations for writing consumables sales information in online through a network  20  to the consumables sales information storage section  107 , using a PC (personal computer)  30 , when manufacturing and shipping the printer  10  by the manufacturer of the printer  10 .  
      In this operations, the manufacturer collects from the seller who sold the printer  10  consumables sales information comprising, for example, the shop name of this seller, the contact details information, information as to the consumables dealt with by this seller or advertising information, and writes the consumables sales information in online into the consumables sales information storage section  107 .  
      As a method of writing consumables sales information by utilizing an interface with a host device (PC  30 ), apart from online writing by a network as described above, writing could be performed using a USB or parallel port. It is also possible to write the consumables sales information using a dedicated application running on the PC  30 .  
      It should be noted that the operations described above of writing consumables sales information by utilizing an interface with a host device (PC  30 ) could also be applied when updating the consumables sales information written by these operations.  
      In the updating processing, updating details (consumables sales information to be updated) are sent together with an updating request through the various types of interface described above (USB, parallel port, or via a network) from the PC  30 .  
      When the printer  10  receives the updating request and updating details transmitted from the PC  30 , the updating processing section  109  is started up in response to the updating request, and processing is performed to update the consumables sales information stored in the consumables information storage section  107  in accordance with the updating details received together with the updating request.  
       FIG. 3  shows an example of writing consumables sales information to the consumable sales information storage section  107  using a dedicated tool  17  having a processing function of writing consumables sales information by the seller who sold the printer  10  manufactured by a manufacturer to the user under a commission from the manufacturer.  
      In this case, when the manufacturer ships the printer  10  to the commissioned seller, the manufacturer provides the dedicated tool  17  (separately provided for each shipping destination) to the seller.  
      In turn, the seller connects the dedicated tool  17  provided by the manufacturer with the external I/F  108  through a communication cable  18  and writes the consumables sales information in respect of consumables sales by the seller&#39;s company to the consumables sales information storage section  107  using the dedicated tool  17 .  
      It should be noted that the method of writing consumables sales information using the dedicated tool  17  could also be applied when updating the consumables sales information that was written by this method.  
      In such updating processing, the details to be updated (consumables sales information to be updated) are sent together with an updating request from this dedicated tool  17  in a condition with this dedicated tool  17  connected to the printer  10  in the mode described above.  
      In response thereto, when the printer  10  receives this updating request and updating details sent from the dedicated tool  17 , the updating processing section  109  is started up in response to this updating request and processing is performed to update the consumables sales information already stored in the consumables information storage section  107  with the updating details received together with this updating request.  
      As described above, the printer  10  in which the consumables sales information is stored by the manufacturer (see  FIG. 2 ) or the seller (see  FIG. 3 ) is then sold from this seller to the user.  
      After purchasing the printer  10  from the seller and commencing use thereof, the user can print out onto a recording medium the consumables sales information (stored in the consumables sales information storage section  107 ) using the consumables sales information printing function described above which is provided in the printer  10 .  
       FIG. 4  shows an example of the environment in which the user uses the printer  10 .  
      In  FIG. 4 , the printer  10  is connected with a PC  30   a  (PC used by a user) through a network  20   a  by means of a network I/F  101 .  
      In this condition, the user can print document information generated by various types of application on the PC  30   a  by sending this document information to the printer  10  by issuing printing commands with the properties of the printer driver.  
      In the printer  10  in such an environment of use, in order to print the consumables sales information, there are available, for example, the method of starting up printing triggered by an input command (trigger 1) in response to a specified manual control operation performed using the manual control section  102  by the user himself, the method of starting up printing triggered (trigger 2) by a printing request issued through the network  20   a  from this PC  30   a  in response to a manual operation of the PC  30   a  (host device) performed by the user himself, and the method of starting up printing automatically by the printer  10  triggered by (trigger 3) output of detection of an event relating to the state of consumption of the consumables by a consumption detection section  110  of the printer  10 .  
      Consumables sales information printing operation using these three methods of starting up printing with the printer  10  will now be described with reference to the flow chart shown in  FIG. 5 .  
      As shown in  FIG. 5 , in the printer  10 , the control section  111  checks (step S 501 ) to ascertain whether or not a specified control operation (switch operation) has been performed at the manual control section  102 .  
      The specified control operation that is the subject of this checking is, for example, a predetermined switch operation to give a command for printing the consumables sales information, such as, for example, independent operation of a given specified switch (consumables sales information printing switch) or a combined operation of a plurality of switches.  
      If, at this point, the specified control operation has not been performed (step S 501  NO), the control section  111  then checks to ascertain whether or not a request for printing the consumables sales information has been issued from the PC  30   a  (step S 502 ).  
      Further, if no such request for printing the consumables sales information has been made (step S 502  NO), the control section  111  then checks to ascertain whether or not an event relating to the condition of consumption of the consumables has been detected by the consumption detection section  110  (step S 503 ), such as, for example, insufficiency of the remaining amount of toner or contamination of the drum cartridge.  
      Thereupon, if no such event has been detected (step S 503  NO), the control section  111  returns to step S 501  and continues checking processing of the steps S 501  to S 503 .  
      In this process, in step S 501  above, if a specified control operation is performed at the manual control section  102  (step S 501  YES), the control section  111  reads (step S 505 ) the consumables sales information from the consumables sales information storage section  107  and transfers this information to the image processing section  104 .  
      The image processing section  104  generates printing data by image processing of this consumables sales information and sends this printing data to the image forming section  105 .  
      The image forming section  105  prints the consumables sales information corresponding to this printing data on the recording medium  15  in accordance with the printing data sent from the image processing section  104  and discharges this recording medium  15  (step S 506 ).  
      Also, in the above step S  502 , if a request for printing the consumables sales information is input from the PC  30   a  (step S 502  YES), the control section  111 , if a specified control operation is performed at the manual control section  102  (step S 501  YES) performs processing in the same way as hereinbelow.  
      In this case, the control section  111  exercises control so as to read the consumables sales information (step S 505 ) from the consumables sales information storage section  107  and print out (step S 506 ) this consumables sales information onto the recording medium by means of the image forming section  105 , by image processing performed by the image processing section  104 .  
      Also, in the above step S 503 , if an event relating to the consumption condition of the consumables such as insufficiency of the remaining amount of toner is detected by the consumption detection section  110  (step S 503  YES), the control section  111  reads the consumables sales information (step S 504 ) corresponding to this detected event from the consumables sales information storage section  107  and transfers this consumables sales information to the image processing section  104 .  
      The image processing section  104  generates printing data by performing image processing on this consumables sales information and sends this printing data to the image forming section  105 .  
      The image forming section  105  prints the consumables sales information corresponding to this printing data on the recording medium  15  in accordance with the printing data sent thereto from the image processing section  104  and discharges this recording medium  15  (step S 506 ).  
      In this way, the printer  10  according to the present embodiment can print consumables sales information on a recording medium  15  by going through the processing shown in  FIG. 5 .  
      The results of printing out the consumables sales information will be further described in detail below with regard to some specific examples.  
       FIG. 6  illustrates a first example of the results of outputting consumables sales information.  
      On the recording medium  15   a  constituting the output results in this example, as the consumables sales information, there are printed advertising information promoting purchase of the consumables (section enclosed by the dotted line), various items of information such as the company name, address, and contact details of the seller who sells the consumables and consumables list information comprising various items such as the consumables name, model number, order number, cost, compatible printer types and discount of the consumables sold by this seller.  
      Using the recording medium  15   a  on which the consumables sales information with the above details has been printed, the user selects, for example, the desired consumables required for the printer  10  which the user is currently using from the printed list of consumables and can thus order this consumables from the seller using, for example, fax, telephone, e-mail or the Web, based on the contact details information (fax number, telephone number, e-mail address, Web address etc).  
       FIG. 7  illustrates a second example of the results of output of the consumables sales information.  
      This second example corresponds to the results of printing and output of consumables sales information read (step S 504  in  FIG. 5 ) from the consumables sales information storage section  107 , for example, in response to event detection of insufficiency of the remaining amount of toner by the consumption detection section  110  (YES in step S 503  in  FIG. 5 ).  
      On the recording medium  15   b  which is the result of output in this example, consumables sales information is printed, including notification information (section within the dotted line) to the effect that the remaining amount of toner is low and prompting purchase of toner, various items of information such as the company name, address and contact details of the seller who sells the toner, and list information of consumables (toner) sold by this seller.  
      Apart from information as to the consumables name, model number, order number, cost, and compatible printer types, the item information in the consumables list includes information for indicating whether this consumables is a new product, old stock, recycled product, high-performance product, small-capacity product or large-capacity product.  
      Using the recording medium  15   b  on which the consumables sales information with the above details has been printed, the user is able to ascertain whether the remaining amount of toner has become low by checking the above notification information, and can immediately determine whether it is necessary to order more toner.  
      Furthermore, the various types of toner that are applicable to the printer  10  that is currently used by the user are printed in the form of consumables (toner) list on this recording medium  15   b.    
      In this way, after the user has selected the desired type of toner, such as new product, old stock, recycled product, high-performance product, small-capacity product or large-capacity product from the consumables (toner) list, the user can order this consumables of from the seller using, for example, fax, telephone, e-mail or the Web, based on the contact details information (fax number, telephone number, e-mail address, Web address etc).  
      In this case, the user can select the toner to be ordered from new products, old stock, recycled products, high-performance products, small-capacity products or large-capacity products also taking price into account so that the choice of consumables that can be ordered is wider than in the case of the first example.  
       FIG. 8  illustrates a third example of the results of output of consumables sales information.  
      In this third example, the consumables sales information is printed out onto a recording medium in the form of consumables order document for fax transmission, for example.  
      On the recording medium  15   c  which is the result of output in this example, as the consumables sales information, there is printed information such as boxes to be filled in of header information of the consumables order document, address information of the consumables order destination for fax transmission [company name and fax number and telephone number of the seller (i.e. the seller who sold the printer  10 ) who sells the consumables], notification information including boxes to be filled in representing the details of the order (order number, number of items, cost) and ordering sequence or notification details, and various items of information relating to the issuer of the order (the user) and the printer used (the printer  10  in question) (the customer&#39;s address, name and ID) of the printer used).  
      Using the recording medium  15   c  on which is printed the consumables sales information with the above content (consumables order document), after entering in the appropriate respective boxes of this consumables order document the order number of the desired consumables, the number of items, the cost and the user&#39;s own address, name, and ID of the printer  10  used, the user can place an order for the desired consumables extremely easily simply by fax transmission of this consumables order document to the corresponding fax number.  
      In all of the first to the third examples, the consumables sales information that is printed out on the recording media  15  ( 15   a ,  15   b ,  15   c ) includes various items of information such as the company name and contact details of the seller who sold the printer  10  that delivered this printed output, consumables name, name of the type of printer, and model number of the applicable consumer product.  
      The user can therefore order from the seller where the user purchased the printer  10  the desired consumables using the contact information printed on the recording medium  15  while viewing this information printed thereon.  
      If the recording medium  15   c  according to the third example is used, the ordering process can be greatly simplified, since this can be simply transmitted by fax as an order document to the seller.  
      Furthermore, the competitiveness of the seller in regard to other sellers can be increased, since the user who purchased the printer  10  sold by the seller&#39;s company can be clearly made aware of the seller&#39;s company as a possible choice for ordering of consumables by this user, by means of the consumables information that is printed out by means of the printer  10 .  
      A method of selling consumables according to the present embodiment based on the above-described construction and mode of use of the printer  10  is described below.  
       FIG. 9  illustrates the flow of sale of consumables using a printer  10  according to the present embodiment. It should be noted that, although only a single seller is mentioned in  FIG. 9 , there could be a plurality of sellers.  
      As shown in  FIG. 9 , in selling consumables according to the present embodiment, the manufacturer who manufactures the printer  10  and the various types of consumables  13  (toner etc) used by the printer  10  and the seller who sells printers  10  and consumables manufactured by this manufacturer co-operate in selling to the user of consumables used by the printer  10 .  
      As described above, a printer  10  manufactured by the manufacturer comprises consumables sales information storage section  107  that stores consumables sales information D 1  including, for example, the contact details of the seller, the seller&#39;s sales advertising for consumables and a list of consumables handled by the seller, and also a printing function that prints out this consumables sales information D 1  onto a recording medium  15 .  
      In sales of the consumables, in a method as indicated, for example, in  FIG. 2 , the manufacturer, when manufacturing and shipping the printer  10 , stores consumables sales information D 1  online in the consumables sales information storage section  107  before selling the printer  10  to the seller.  
      In performing this, the manufacturer collects beforehand information such as the company name and contact details from the seller and the necessary information for selling the consumables and uses this collected information to create the consumables sales information D 1 , which is then stored.  
      The manufacturer manufactures various types of consumables  13  that are used by the printer  10  and sells these consumables to the seller in response to orders from the seller.  
      The seller purchases from the manufacturer printers  10  in which there is recorded consumables sales information D 1  relating to sale of consumables including the contact details of the seller&#39;s company, and sells these printers  10  on to the user.  
      It should be noted that the task of storing the consumables sales information D 1  in the consumables sales information and storage section  107  of the printer  10  described above need not be performed by the manufacturer. It could be performed by the seller itself.  
      In this case, the manufacturer provides to the seller on shipping of the printer  10  a dedicated tool  17  for consumables sales information storage processing and the seller, using the dedicated tool  17 , by, for example, the method shown in  FIG. 3 , stores the consumables sales information D 1  of the seller&#39;s company in the consumables sales information storage section  107  of the printer  10 .  
      In this way, after the seller has sold to the user a printer  10  in which is stored the consumables sales information D 1  in the consumables sales information storage section  107  by either the manufacturer or the seller, the seller can expect orders for consumables  13  to be placed using the consumables sales information D 1  printed out by the user to whom the sale was made using the printer  10 .  
      The user performs printing using the printer  10  purchased from the seller, and, during the course of such use, reads the consumables sales information D 1  from the consumables sales information storage section  107  using, for example, a printing start-up command corresponding to the triggers  1  to  3  shown in  FIG. 4  and prints out this consumables sales information D 1  onto the recording medium  15  (see, for example,  15   a ,  15   b  and  15   c  shown in  FIG. 6 ,  FIG. 7  and  FIG. 8 ).  
      The user then places an order for the desired consumables  13  as required with the seller, while viewing the consumables sales information D 1  printed on this recording medium  15 .  
      If the consumables sales information D 1  is printed in a mode such as on a recording medium  15   a  as shown in  FIG. 6 , the user can access the seller&#39;s PC  30   b  from a PC  30   a  (or may communicate by telephone) using this contact details information (for example e-mail address or Web address) and order from the seller the desired consumables  13  selected from the consumables list that is simultaneously printed.  
      Also, if the consumables sales information D 1  is printed on a recording medium  15  ( 15   c ) in the form of consumables order document as shown in  FIG. 8 , the user can order the consumables  13  by entering the desired order details (order number and number of items and cost etc of the consumables  13 ) in this consumables order document and transmitting this form by fax, from a fax  40   a , to the fax  40   b  of the seller, which is given in this order document.  
      In this regard, when the seller, as described above, after selling the printer  10  to the user, receives an order for consumables  13  by telephone, URL or fax based on the consumables sales information D 1  that was printed out to the recording medium  15  by the user using the printer  10 , the seller is able to make arrangements for dispatch of the consumables  13  that has thus been ordered and sell this consumables  13  to the user.  
      As described above, with the method of selling consumables according to the present embodiment, since the consumables sales information relating to sale of the consumables that is handled by this seller is stored in the printer  10  that is sold to the user by the seller, the user can place an order for the consumables using the consumables sales information that is printed out by the printer  10 , thereby increasing convenience of ordering consumables for the user, without requiring, for example, access to the Internet.  
      Also, the seller can induce a user who purchased a printer  10  from this seller to place orders for consumables to this seller using this consumables sales information that is printed out, through the printing and output of the consumables sales information by the printer  10 ; in this way, competitiveness of the seller with respect to other sellers can be improved and sales promoted.  
      Furthermore, the manufacturer can expect a considerable increase in profitability by increasing the amount of sales of the consumables manufactured by the manufacturer in response to promotion of sales of the consumables by the seller.  
      It should be noted that it is desirable that the content of the consumables sales information that is printed by the user using the printer  10  purchased from the seller&#39;s company should be a content such as to facilitate ordering from the seller&#39;s company, in order to achieve firmer tying-in of users by the seller.  
      Consumables sales information satisfying this condition should be structured so as to promote feelings of a human relationship by emphasizing recency and appealing to users&#39; emotion, or by increasing the costs of switching to other sellers, for example.  
      From this point of view, in the present invention, the following expedients may be adopted regarding the content of the consumables sales information.  
      For example, where the consumables is toner, the consumables sales information employed according to the present embodiment may offer a discount depending on the remaining amount of toner, so as to achieve the advantage of the “first move” in consumables replacement (see  FIG. 7 ).  
      Also, by specifying the consumables purchase point, barriers to ordering by the user are lowered (see  FIG. 6 ,  FIG. 7  and  FIG. 8 ).  
      Also, by arranging for notification of the model number, opportunities for choice can be provided to the user, such as facilitating the provision of clearance products (recycled products, old stock) for other compatible printers, or provision of the latest toner (new product) (see  FIG. 7 ).  
      As can be seen from the results of printout of consumables sales information shown in  FIG. 6  to  FIG. 8 , and since the consumables sales information stored in the consumables sales information at storage section  107  of the printer  10  according to the present embodiment includes advertising information promoting purchase of consumables from the seller&#39;s company, the seller who sold the printer  10  can treat the consumables sales information storage section  107  in which the advertising information is stored as a kind of advertising space.  
      From this point of view, as a business model (first business model) employing the method of selling consumables according to the present embodiment, the model that the manufacturer sells (i.e., provides for a consideration) an advertising space corresponding to the consumables sales information storage section  107  of the printer  10  to the seller can be also envisaged.  
      Also, taking into consideration the fact that the manufacturer provides the seller with the dedicated tool  17  whereby the seller itself can write/update (see  FIG. 3  and  FIG. 9 ) advertising information (consumables sales information) in the consumables information storage section  107  (advertising space) of the printer  10 , a business model (second business model) is also envisageable in which the dedicated tool  17  for writing the seller company&#39;s own advertising information is sold to the seller by the manufacturer (provided for a consideration) in a form requiring, for example, a commitment to a sales number of printers  10 .  
       FIG. 10  illustrates the transaction flow in the above first business model.  
      In  FIG. 10 , the manufacturer sells the consumables sales information storage section  107  of the printer  10  manufactured by the manufacturer&#39;s company to the various sellers A, B, C as advertising space, and obtains payment for the cost therefor.  
      Also, the manufacturer collects respective advertising information (consumables sales information) from the sellers A, B, C (see  FIG. 3  and  FIG. 9 ) to whom the advertising space is sold and ships (sells) the corresponding printers  10  to the sellers A, B, C after storing this information in the consumables sales information storage section  107  of the printers  10  destined for the respective sellers, and obtains payment for the cost therefor.  
      The sellers A, B, C sell the printers  10  purchased from the manufacturer to the users. The sellers A, B, C then respectively receive orders for consumables placed using the consumables sales information printed out by the users to whom the printers are sold, using the users&#39; own printers  10 ; the flow of sales of these consumables to the users is as described in  FIG. 9 .  
       FIG. 11  illustrates the transaction flow in the second business model referred to above.  
      In  FIG. 11 , the manufacturer manufactures the printers  10  having an advertising space (consumables information storage section  107 ) and a function of printing out advertising information (consumables sales information) stored in this advertising space and ships (sells) these to the sellers A, B, C and obtains payment for the cost therefor.  
      Also, the manufacturer sells to the sellers A, B, C a dedicated tool  17  for writing (including updating) advertising information (consumables sales information) into this advertising space of the printer  10  (consumables information storage section  107 ) when these printers  10  manufactured by the manufacturer&#39;s company are shipped, and obtains payment for the cost therefor.  
      The sellers A, B, C respectively write advertising information (consumables sales information) using the dedicated tool  17  purchased from this manufacturer into the advertising space (consumables sales information storage section  107 ) of the printers  10  purchased from the manufacturer before selling these printers  10  on to the users.  
      The sellers A, B, C then respectively receive orders for consumables placed using the consumables sales information printed out, by the users to whom the printers are sold, using the users&#39; own printers  10 ; the flow of sales of these consumables to the users is as described in  FIG. 9 .  
      Thus, according to the present embodiment, by providing advertising space in local printing by the printers  10 , for example, by selling the advertising space only to a number of company customers such as large-scale sellers (i.e. “partners”), the sales competitiveness of such customers can be increased, thereby promoting sales of printers  10  manufactured by the manufacturer&#39;s company.  
      In this way, the manufacturer may also expect increased profitability due to sales of the advertising space or dedicated tool  17 .  
      Apart from this, the present invention is not restricted to the embodiments described above and may be put into practice in suitably modified ways without altering its gist.  
      For example, in the above embodiments, as the consumables sales information stored in the consumables sales information storage section  107  of the printer  10 , an amount thereof corresponding to one page of an A4 size recording medium  15  is envisioned.  
      However, the consumables sales information is not restricted to the aforementioned amount and the content thereof is also not restricted to the content shown in  FIG. 6  to  FIG. 8 .  
      Also, the consumables to be sold are not restricted to the toner mentioned in the above embodiments (in fact, what is sold is a toner cartridge) and various types of consumables such as photosensitive drum units or recording paper may be envisioned.
