Abstract

In a print system of this invention, upon issuance of a preview instruction from an application (201), print data is spooled in a spool file (303). A printer driver (203) despools the spooled data and transmits the despooled data to a printer (2000) as a preview job together with job setting information. The printer (2000) generates preview information for each physical page in accordance with the job setting information, and sends it to a host computer (3000). A previewer (306) receives the preview information, reads out data from a spooler, and displays a preview image in accordance with the received preview information.

Claims

1. An information processing apparatus comprising:

a spool unit constructed to spool intermediate code generated based on a print request from an application;

a preview unit constructed to read the spooled intermediate code and issue a print instruction; and

a printer driver unit constructed to generate PDL commands based on the print instruction from the preview unit, and transmit a preview job to a printer, which is formed with the PDL commands and a preview attribute attached to the PDL commands, the PDL commands being generated based on the intermediate code;

wherein the printer parses the preview job transmitted from the printer driver unit, creates preview information including a layout for each physical page and transmits the preview information including the layout for each physical page,

wherein the preview unit receives the preview information including the layout for each physical page, which is transmitted from the printer based on the preview job, and

wherein the preview unit reads the spooled intermediate code, and performs previewing based on the read intermediate code and the preview information received from the printer.

2. The apparatus according to claim 1, wherein the preview information further includes page configuration information indicating rotation of a page of which an orientation is different from other pages with maintenance of its size when 2-up printing, or page configuration information indicating reduction of a page of which an orientation is different from other pages with maintenance of its orientation when 2-up printing.

3. The apparatus according to claim 1, wherein the printer generates the preview information by performing a RIP processing when a blank page determination or a color/monochrome determination is included.

4. The apparatus according to claim 1, further comprising a modification unit constructed to modify the print settings based on the preview information in response to an instruction from a user,

wherein said preview unit performs previewing based on the modified print settings.

5. The apparatus according to claim 1, wherein the preview unit reflects the print settings in job setting information of the preview job in response to a change of the print settings made after previewing, and transmits the print instruction to the printer driver unit, and

the printer driver unit generates difference PDL commands and transmits the generated difference PDL commands to the printer.

6. An information processing method that is executed by an information processing apparatus, said method comprising:

spooling intermediate code generated based on a print request from an application;

by a preview unit, reading the spooled intermediate code and issuing a print instruction;

by a printer driver unit, generating PDL commands based on the print instruction from the preview unit, and transmitting a preview job to a printer, which is formed with the PDL commands and a preview attribute attached to the PDL commands, the PDL commands being generated based on the intermediate code;

by the printer, parsing the preview job transmitted from the printer driver unit, creating preview information including a layout for each physical page and transmitting the preview information including the layout for each physical page;

by the preview unit, receiving the preview information including the layout for each physical page, which is transmitted from the printer based on the preview job; and

by the preview unit, reading the spooled intermediate data, and performing previewing based on the read intermediate code and the preview information received from the printer.

7. The method according to claim 6, wherein the preview information further includes page configuration information indicating rotation of a page of which an orientation is different from other pages with maintenance of its size when 2-up printing, or page configuration information indicating reduction of a page of which an orientation is different from other pages with maintenance of its orientation when 2-up printing.

8. The method according to claim 6, wherein the printer generates the preview information by performing a RIP processing when a blank page determination or a color/monochrome determination is included.

9. The method according to claim 6, further comprising modifying the print settings based on the preview information in response to an instruction from a user,

wherein previewing is performed based on the modified print settings.

10. The method according to claim 6, further comprising the steps of:

by the preview unit, reflecting the print settings in job setting information of the preview job in response to a change of the print settings made after previewing, and transmitting the print instruction to the printer driver unit; and

by the printer driver unit, generating difference PDL commands and transmitting the generated difference PDL commands to the printer.

11. A non-transitory computer-readable storage medium storing a computer-executable program for causing an information processing apparatus to perform a method, the method comprising:

a spool step for spooling intermediate code generated based on a print request from an application;

by a preview unit, reading the spooled intermediate code and issuing a print instruction;

by a printer driver unit, generating PDL commands based on the print instruction from the preview unit, and transmitting a preview job to a printer, which is formed with the PDL commands and a preview attribute attached to the PDL commands, the PDL commands being generated based on the intermediate code;

by the printer, parsing the preview job transmitted from the printer driver unit, creating preview information including a layout for each physical page and transmitting the preview information including the layout for each physical page;

by the preview unit, receiving the preview information including the layout for each physical page, which is transmitted from the printer based on the preview job; and

by the preview unit, reading the spooled intermediate code, and performing previewing based on the read intermediate code and the preview information received from the printer.

12. The non-transitory computer-readable storage medium storing a computer-executable program of claim 11, wherein the preview information further includes page configuration information indicating rotation of a page of which an orientation is different from other pages with maintenance of its size when 2-up printing, or page configuration information indicating reduction of a page of which an orientation is different from other pages with maintenance of its orientation when 2-up printing.

13. The non-transitory computer-readable storage medium storing a computer-executable program of claim 11, wherein the printer generates the preview information by performing a RIP processing when a blank page determination or a color monochrome determination is included.

14. The non-transitory computer-readable storage medium storing a computer-executable program of claim 11, the method further comprising modifying the print settings based on the preview information in response to an instruction from a user,

wherein previewing is performed based on the modified print settings.

15. The non-transitory computer-readable storage medium storing a computer-executable program of claim 11, wherein the method further comprises the steps of:

by the preview unit, reflecting the print settings in job setting information of the preview job in response to a change of the print settings made after previewing, and transmitting the print instruction to the printer driver unit; and

by the printer driver unit, generating difference PDL commands and transmitting the generated difference PDL commands to the printer.
