Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a printing apparatus for printing print data on an original and a duplicate copy according to a duplicate command sent from a host device. 
     A conventional printing apparatus such as a ticket printer prints on a medium such as a ticket. When such a printing apparatus performs duplicate printing according to a copy command sent from a host device, the printing apparatus prints on a plurality of sheets with same print quality (refer to Patent Reference). 
     Patent Reference: Japanese Patent Publication No. 08-72325 
     When the conventional printing apparatus prints on a plurality of sheets with same print quality, an excess amount of toner is consumed. In the duplicate printing, the first sheet is sent to a client or a customer, and subsequent sheets are for distribution and record. Accordingly, the subsequent sheets do not need to be printed with high quality. However, in the conventional printing apparatus, a plurality of sheets having same print quality is printed, thereby consuming an excess amount of toner. 
     In view of the problems described above, an object of the invention is to provide a printing apparatus, in which it is possible to solve the problems in the conventional printing apparatus. More specifically, when a duplicate command is received from a host device, the printing apparatus prints on an original with quality according to the duplicate command sent from the host device and prints on a duplicate copy with lower quality, thereby conserving toner. 
     Further objects of the invention will be apparent from the following description of the invention. 
     SUMMARY OF THE INVENTION 
     In order to attain the objects, according to the present invention, a printing apparatus receives print data from a host device, and performs a printing operation according to the print data. The printing apparatus may be capable of printing in a plurality of colors. The printing apparatus includes a duplicate printing unit for printing on an original and a duplicate copy according to the print data through a duplicate command from the host device; and a duplicate command detection unit for detecting the duplicate command of the print data. When the duplicate command is detected, the duplicate printing unit prints on the original according to the duplicate command sent from the host device, and prints on the duplicate copy in monochrome. 
     In the printing apparatus according to the present invention, when the duplicate command is detected, the duplicate printing unit prints on the original according to the duplicate command from the host device, and prints on the duplicate copy with lower quality. Accordingly, it is possible to reduce a consumed amount of developer.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Hereunder, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 
     First Embodiment 
     A first embodiment of the present invention will be explained next.  FIG. 1  is a schematic view showing a print result of an original and a duplicate copy according to the first embodiment of the present invention.  FIG. 2  is a schematic view showing a configuration of a system according to the first embodiment of the present invention. 
     As shown in  FIG. 2 , a printing apparatus  40  is connected to a host device  30  as an upper device thereof through a communication line such as an interface cable and the likes. According to the embodiment of the present invention, the printing apparatus  40  includes any devices capable of forming an image on a medium through an electric-photography process. For example, the printing apparatus  40  may include a facsimile and a copier. 
     The printing apparatus  40  may be a monochrome printer for forming a monochrome image, i.e., an image in one color. In the embodiment, the printing apparatus  40  is a color printer capable of forming a color image, i.e., an image in multiple colors. Also, it is supposed that the printing apparatus  40  is a device for printing on media such as invoices, tickets, and the likes. 
     In the printing apparatus  40 , developer images formed of developer in colors are formed on developer image supporting members in four image forming units corresponding to four colors, i.e., yellow, magenta, cyan, and black. The developer images are transferred to a medium, thereby forming a color image on the medium. 
     In the embodiment, the host device  30  is a computer such as a personal computer, a server, and the likes having an operation device such as a CPU, an MPU, and the likes; a storage device such as a hard disk, a semiconductor memory, and the likes; an input device such as a keyboard, a mouse, a touch panel, and the likes; and a display device such as a CRT, a liquid crystal display, and the likes. Further, the host device  30  may include a device capable of generating print data that enables the printing apparatus  40  to perform a printing operation. 
     In general, even when a plurality of copies is printed, a purpose or value of each copy may vary. For example, in many cases, only one copy is stored for record as an original, and other copies may be printed in monochrome without any problem. In the embodiment of the present invention, an original is printed in colors with high quality sufficient for record purpose, and other duplicate copies (rest of print outs) are printed in monochrome, thereby conserving toner. 
     As shown in  FIG. 1 , an original print medium  10  is a medium printed in colors as an original, and a duplicate copy medium  20  is a medium printed in monochrome as a duplicate copy. The print data received from the host device  30  includes, for example, a color text  11 , a monochrome text  12 , and a color image  13 . On the original print medium  10 , the color text  11  is printed in colors; the monochrome text  12  is printed in monochrome; and the color image  13  is printed in colors. In contrast, on the duplicate copy medium  20 , the color text  11  is printed in monochrome as a monochrome text  21 ; the monochrome text  12  is printed in monochrome as is; and the color image  13  is printed in monochrome as a monochrome image  23 . 
     The host device  30  includes an application  31  for creating the print data and the likes, and a printer driver  32  for directing the printing apparatus  40  to perform a printing operation. The printer driver  32  includes a duplicate command unit  32   a  for conducting print setting of the original print medium  10  and the duplicate copy medium  20 . 
     In the embodiment, the printing apparatus  40  includes a reception and decode processing unit  41 ; an edition and deployment processing unit  42 ; a print processing unit  43 ; a panel input device  44 ; and a duplicate setting unit  45 . The reception and decode processing unit  41  receives the print data sent from the host device  30  and decoded the print data thus received. The reception and decode processing unit  41  includes a duplicate command detection unit  41   a  as a duplicate direction detecting unit for detecting a duplicate direction of the print data or a duplicate command sent from the host device  30 . 
     In the embodiment, the duplicate setting unit  45  sets and stores duplicate command information according to the duplicate command detected by the duplicate command detection unit  41   a,  and directs the edition and deployment processing unit  42  to conduct duplicate printing. Further, the duplicate setting unit  45  includes a data storage unit  45   a  for storing the print data to be used one more time for the duplicate printing. 
     In the embodiment, the panel input device  44  processes a mode input through an operation panel (not shown) provided in the printing apparatus  40 . An operator may operate the operation panel to directly input the duplicate command information. 
     In the embodiment, the edition and deployment processing unit  42  converts the print data decoded by the reception and decode processing unit  41  to a bitmap image that can be printed. Further, the edition and deployment processing unit  42  includes a color/monochrome conversion unit  42   a,  so that the color/monochrome conversion unit  42   a  converts a color command to a monochrome command when the duplicate command is received from the duplicate setting unit  45 . 
     In the embodiment, the print processing unit  43  prints the print data converted to the bitmap image on a medium. Note that the edition and deployment processing unit  42 , the print processing unit  43 , and the duplicate setting unit  45  constitute a duplicate printing unit for printing on the original and the duplicate copy according to the print data through the duplicate command sent from the host device  30 . 
     An operation of the printing apparatus  40  will be explained next. An operation of setting the duplicate command will be explained first.  FIG. 3  is a schematic view showing an example of a duplicate command display  51  of the printer driver  30  according to the first embodiment of the present invention.  FIG. 4  is a schematic view showing an example of the duplicate command according to the first embodiment of the present invention. 
     In the embodiment, the duplicate command specifying the number of copy sets is set through the panel input device  44  or the host device  30 . Then, the first sheet is printed in colors normally as the original, and the subsequent sheets are printed in monochrome as the duplicate copies. In the following description, the duplicate command is assumed to be set through the host device  30 . 
     As shown in  FIG. 3 , the duplicate command display  50  of the host device  30  has a duplicate print box  51 , and the duplicate print box  51  is checked to set the duplicate command through the host device  30 . It is possible to specify the number of copy sets  52  and whether the printing is conducted per copy set  53 . 
     When the duplicate command is set as described above, the duplicate command shown in  FIG. 4  is sent from the host device  30  to the printing apparatus  40 . 
     An operation of the duplicate printing of the printing apparatus  40  will be explained next.  FIG. 5  is a schematic view showing an example of the duplicate command information according to the first embodiment of the present invention.  FIG. 6  is a schematic view showing an example of a color/monochrome specifying command according to the first embodiment of the present invention.  FIG. 7  is a flow chart of the operation of the duplicate printing of the printing apparatus  40  according to the first embodiment of the present invention. 
     When the reception and decode processing unit  41  of the printing apparatus  40  receives the print data from the host device  30 , the reception and decode processing unit  41  decodes the print data, i.e., performs reception and decode processing. The duplicate command detection unit  41   a  determines whether the duplicate command exists in the print data sent from the host device  30 . As shown in  FIG. 4 , the duplicate command includes information such as a duplicate mode, the number of copy sets, and the mode of printing per copy set. 
     When the duplicate command exists in the print data, as shown in  FIG. 5 , the duplicate setting unit  45  sets the duplicate command information including the duplicate mode, the number of copy sets, and the mode of printing per copy set according to the duplicate command. 
     In the duplicate command information, when the duplicate command does not exist, the duplicate mode is designated as 0. When the duplicate command exists, the duplicate mode is designated as 1. The number of copy sets indicates the number of copy sets to be printed. When the mode of printing per copy set is activated, the mode of printing per copy set is designated as 1. When the mode of printing per copy set is not activated, the mode of printing per copy set is designated as 0. 
     In the duplicate printing, it is necessary to read the print data one more time. Accordingly, it is arranged such that the print data or received data is stored in the data storage unit  45   a.    
     In the next step, the edition and deployment processing unit  42  retrieves the print data stored in the data storage unit  45   a,  and performs edition and deployment processing for converting the print data to the printable bitmap image. Then, the print processing unit  43  performs print processing for printing the print data converted to the bitmap image on a medium. 
     The duplicate command detection unit  41   a  determines whether there is the duplicate command through the duplicate mode in the duplicate command information. When the duplicate mode is activated, the duplicate setting unit  45  sets a monochrome specifying command (ESC &amp; b 1 M) in the color/monochrome specifying command shown in  FIG. 6 , so that the monochrome specifying command is added to the received data. Accordingly, the edition and deployment processing unit  42  is directed to perform the monochrome printing on subsequent sheets. 
     In the next step, the edition and deployment processing unit  42  retrieves the stored data for printing the duplicate copy, and reads the received data from the data storage unit  45   a  one more time. While the edition and deployment processing unit  42  reads the received data, the color/monochrome conversion unit  42   a  determines whether the color specifying command (ESC &amp; b 0 M) is detected. When the color specifying command (ESC &amp; b 0 M) is detected, the color/monochrome conversion unit  42   a  converts the color specifying command (ESC &amp; b 0 M) to the monochrome specifying command (ESC &amp; b 1 M). 
     In the next step, the edition and deployment processing unit  42  performs the edition and deployment processing for converting the received data to the printable bitmap image, thereby creating the bitmap image for the monochrome printing. 
     In creating the bitmap image, for example, when color data is input in a CMY format, values of C, M, and Y corresponding to each pixel multiplied by coefficients are added to create monochrome data corresponding to the pixel. For example, the monochrome data may be a sum of the value of C multiplied by 0.3, the value of M multiplied by 0.6, and the value of Y multiplied by 0.1. 
     The conversion described above is repeated for all pixels, so that the monochrome data is created from the color data. Then, the print processing unit  43  performs the print processing on the medium according to the print data converted to the bitmap image, thereby performing the monochrome printing. 
     In the next step, it is determined whether the number of copy sets is completed. When the number of copy sets is completed, the printed media are discharged, thereby competing the process. When the number of copy sets is not completed, the process described above is repeated. That is, when the number of copy sets in the duplicate command information is more than one, the process is repeated for the specified number. When the duplicate mode in the duplicate command information is not activated, i.e., the duplicate printing is not specified, only the original is printed, and the print data is deleted after the printed medium is discharged. 
     As described above, in the embodiment, the color printing is converted to the monochrome printing, thereby conserving developer. In the monochrome printing, a print processing time is reduced. Further, a toner layer on a medium is singular. Accordingly, it is assumed that a fixing time of the monochrome printing is same as that of the color printing, it is possible to stably fix an image at a higher transporting speed. As a result, it is possible to reduce a print processing time by increasing a transporting speed, thereby improving productivity. 
     In the embodiment, it is possible to perform the monochrome printing using developer having a largest remaining amount among multiple colors. In the case of yellow, since yellow is not distinguishable, it is preferred to perform printing with shadow, printing with frame, two-color printing, and the likes. In general, the monochrome printing is performed at a furthermost location on a downstream side of the image forming unit in a transportation direction, thereby eliminating smear in the image forming unit due to developer. 
     In the embodiment, when a plurality of copy sets is specified through the host device  30 , the first set is printed in colors normally as an original, and the subsequent sets are printed in monochrome as duplicate copies. For example, when the print data includes data of five pages, the first set having five pages is printed in colors. The subsequent sets having five pages are printed in monochrome. Further, it is possible to print the first page of the first set in colors and the first pages of the subsequent sets in monochrome. Then, the second page of the first set is printed in colors, and the second pages of the subsequent sets are printed in monochrome. The following pages are printed in the same way. 
     The flow chart shown in  FIG. 7  will be explained next. In step S 1 , the reception and decode processing is performed. In step S 2 , it is determined whether the duplicate command exists. When the duplicate command exists, the process proceeds to step S 3 . When the duplicate command does not exist, the process proceeds to step S 5 . 
     In step S 3 , the duplicate command information is set. In step S 4 , the received data is stored. In step S 5 , the edition and deployment processing of the original is performed. In step S 6 , the print processing is performed. In step S 7 , it is determined whether the duplicate command exists. When the duplicate command exists, the process proceeds to step S 8 . When the duplicate command does not exist, the process is completed. 
     In step S 8 , the monochrome specifying command is set. In step S 9 , the stored data is retrieved. In step S 10 , it is determined whether the color specifying command is detected. When the color specifying command is detected, the process proceeds to step S 11 . When the color specifying command is not detected, the process proceeds to step S 12 . 
     In step S 11 , the color specifying command is converted to the monochrome specifying command. In step S 12 , the edition and deployment processing of the duplicate copy is performed. In step S 13 , the print processing is performed. In step S 14 , it is determined whether the number of copy sets is completed. When the number of copy sets is completed, the process is completed. When the number of copy sets is not completed, the process returns to step S 8 . 
     As described above, in the first embodiment of the present invention, when the number of copy sets is set plural, the original is printed in colors according to the normal print command. The duplicate copy (subsequent set) is printed in monochrome, thereby conserving developer. 
     Second Embodiment 
     A second embodiment of the present invention will be explained next. Components in the second embodiment similar to those in the first embodiment are designated with the same reference numerals, and explanations thereof are omitted. The components and operations similar to those in the first embodiment provide the similar effects, and explanations thereof are omitted. 
       FIG. 8  is a schematic view showing a print result of an original and a duplicate copy according to the second embodiment of the present invention.  FIG. 9  is a schematic view showing a configuration of a system according to the second embodiment of the present invention. 
     In the second embodiment, after the original is printed normally, only necessary texts are printed on the duplicate copy. 
     As shown in  FIG. 8 , an original print medium  60  is a medium printed normally as an original, and a duplicate copy medium  70  is a medium printed as a duplicate copy. The print data received from the host device  30  includes, for example, a standard text  61 , a frame form  62 , an image  63 , and a modification text  64 . On the original print medium  60 , the standard text  61 , the frame form  62 , the image  63 , and the modification text  64  are printed. In contrast, on the duplicate copy medium  70 , standard texts  71  and  72  are printed. 
     In the embodiment, the duplicate command unit  32   a  of the printer driver  32  conducts print setting of the original print medium  60  and the duplicate copy medium  70 . Further, the duplicate setting unit  45  performs a process different from that in the first embodiment. The edition and deployment processing unit  42  includes a specific command reception and discard processing unit  42   b  for performing a reception and discard process of a specific command. Other components in the second embodiment are the same as those in the first embodiment, and explanations thereof are omitted. 
     An operation of the printing apparatus  40  will be explained next. An operation of setting the duplicate command will be explained first.  FIG. 10  is a schematic view showing an example of the duplicate command display  50  of the printer driver according to the second embodiment of the present invention.  FIG. 11  is a schematic view showing an example of the duplicate command according to the second embodiment of the present invention. 
     As shown in  FIG. 10 , the duplicate command display  50  of the host device  30  has the duplicate print box  51 , and the duplicate print box  51  is checked to set the duplicate command through the host device  30 . It is possible to set the number of copy sets  52  and whether the printing is conducted per copy set  53 . When the printing operation is conducted only for texts without the image  63 , a text printing  54  is checked to set the mode. 
     When the duplicate command is set as described above, the duplicate command shown in  FIG. 11  is sent from the host device  30  to the printing apparatus  40 . 
     An operation of the duplicate printing of the printing apparatus  40  will be explained next.  FIG. 12  is a schematic view showing an example of the duplicate command information according to the second embodiment of the present invention.  FIG. 13  is a schematic view showing an example of the color/monochrome specifying command according to the second embodiment of the present invention.  FIG. 14  is a flow chart No. 1 of an operation of the duplicate printing of the printing apparatus according to the second embodiment of the present invention.  FIG. 15  is a flow chart No. 2 of the operation of the duplicate printing of the printing apparatus according to the second embodiment of the present invention. 
     When the reception and decode processing unit  41  of the printing apparatus  40  receives the print data from the host device  30 , the reception and decode processing unit  41  decodes the print data, i.e., performs the reception and decode processing. The duplicate command detection unit  41   a  determines whether the duplicate command exists in the print data sent from the host device  30 . As shown in  FIG. 11 , the duplicate command includes information such as the duplicate mode, the number of copy sets, and the mode of printing per copy set. 
     When the duplicate command exists in the print data, as shown in  FIG. 12 , the duplicate setting unit  45  sets the duplicate command information including the duplicate mode, a text only printing mode, the number of copy sets, and the mode of printing per copy set according to the duplicate command. 
     In the duplicate command information, when the duplicate command does not exist, the duplicate mode is designated as 0. When the duplicate command exists, the duplicate mode is designated as 1. When the text only printing mode is not activated, the text only printing is designated as 0. When the text only printing mode is activated, the text only printing is designated as 1. The number of copy sets indicates the number of copy sets to be printed. When the mode of printing per copy set is activated, the mode of printing per copy set is designated as 1. When the mode of printing per copy set is not activated, the mode of printing per copy set is designated as 0. 
     In the duplicate printing, it is necessary to read the print data one more time. Accordingly, it is arranged such that the print data or received data is stored in the data storage unit  45   a.    
     In the next step, the edition and deployment processing unit  42  retrieves the print data stored in the data storage unit  45   a  for printing on the original, and performs the edition and deployment processing for converting the print data to the printable bitmap image. Then, the print processing unit  43  performs the print processing for printing the print data converted to the bitmap image on a medium. 
     The duplicate command detection unit  41   a  determines whether there is the duplicate command through the duplicate mode in the duplicate command information. When the duplicate mode is activated, i.e., the duplicate command exists, the duplicate setting unit  45  sets the monochrome specifying command (ESC &amp; b 1 M) in the color/monochrome specifying command shown in  FIG. 13 , so that the monochrome specifying command is added to the received data. Accordingly, the edition and deployment processing unit  42  is directed to perform the monochrome printing on subsequent sheets. 
     In the next step, the edition and deployment processing unit  42  retrieves the stored data for printing the duplicate copy, and reads the received data from the data storage unit  45   a  one more time. While the edition and deployment processing unit  42  reads the received data, the color/monochrome conversion unit  42   a  determines whether the color specifying command (ESC &amp; b 0 M) is detected. When the color specifying command (ESC &amp; b 0 M) is detected, the color/monochrome conversion unit  42   a  converts the color specifying command (ESC &amp; b 0 M) to the monochrome specifying command (ESC &amp; b 1 M). 
     When the only text printing mode is activated, a specific command used for advertisement, decoration, appearance, and the likes is received and discarded. The specific command includes an image specifying command for specifying the image  63  such as an image data; a form specifying command for specifying a form such as a frame and the likes; a line specifying command for specifying a line such as an under line, an over line, and the likes; and a decoration command for performing text decoration such as bold, italic, enlargement and the likes. 
     The specific command reception and discard processing unit  42   b  determines whether the specific command exists. When the specific command exists, the specific command reception and discard processing unit  42   b  receives and discards the specific command. When an image transfer command (ESC * b # W) is received during reading the received data, the image data is canceled through the reception and discard processing. 
     In the next step, the edition and deployment processing unit  42  performs the edition and deployment processing for converting the received data to the printable bitmap image. In this case, since the reception and discard processing of the specific command is performed, the bitmap image is created for printing only the text in monochrome. Then, the print processing unit  43  performs the print processing on a medium according to the print data converted to the bitmap image, thereby printing only the text in monochrome. 
     In the next step, it is determined whether the number of copy sets is completed. When the number of copy sets is completed, the printed media are discharged, thereby competing the process. When the number of copy sets is not completed, the process described above is repeated. That is, when the number of copy sets in the duplicate command information is more than one, the process is repeated for the specified number. When the duplicate mode in the duplicate command information is not activated, i.e., the duplicate printing does not exist, only the original is printed, and the received data is deleted after the printed medium is discharged. 
     As described above, in the embodiment, the color printing is converted to the monochrome printing, and the specific command is received and discarded. Accordingly, the bitmap data is created for printing only the text in monochrome, thereby conserving developer. In printing only the text in monochrome, a print processing time is reduced. Further, a toner layer on a medium is singular. Accordingly, when a fixing time is same as that of the color printing, it is possible to stably fix an image at a higher transporting speed. As a result, it is possible to reduce print processing time by increasing a transporting speed, thereby improving productivity. 
     The flow charts shown in  FIGS. 14 and 15  will be explained next. In step S 21 , the reception and decode processing is performed. In step S 22 , it is determined whether the duplicate command exists. When the duplicate command exists, the process proceeds to step S 23 .

     In step S 23 , the duplicate command information is set. In step S 24 , the received data is stored. In step S 25 , the edition and deployment processing of the original is performed. In step S 26 , the print processing is performed. In step S 27 , it is determined whether the duplicate command exists. When the duplicate command exists, the process proceeds to step S 28 .

     In step S 28 , the monochrome specifying command is set. In step S 29 , the stored data is retrieved. In step S 30 , it is determined whether the color specifying command is detected. When the color specifying command is detected, the process proceeds to step S 31 . When the color specifying command is not detected, the process proceeds to step S 32 . In step S 31 , the color specifying command is converted to the monochrome specifying command.
