Printing system and print data rewriting method

Abstract

In accordance with one embodiment, a printing system comprises a memory, a processor and an interface. The processor rewrites the first information contained in the print data stored in the memory and designating a sheet stacking section at an end of a conveyance path of an image forming apparatus. The interface sends the rewritten print data to the image forming apparatus.

What is claimed is: 
     
         1 . A printing system, comprising:
 an image forming apparatus configured to comprise a sheet feed source and a first discharging section which stacks image formed sheets;   a finisher configured to be provided away from the first discharging section to the sheet feed source and connect to the image forming apparatus and comprise a second discharging section which stacks image formed sheets; and   a computer comprising:
 a memory; 
 a reception interface configured to receive a print data which comprises a first information designating the first discharging section or the second discharging section as a sheet discharging destination and a second information designating a post processing; 
 a processor configured to extract the second information from the print data, 
 store the print data in the memory if the post processing is designated in the second information, and 
 rewrite the first information of the print data so that the first discharging section is designated and store the rewritten print data in the memory if none of the post processing is designated in the second information; and 
 a transmission interface configured to transmit the print data stored in the memory to the image forming apparatus. 
   
     
     
         2 . The printing system according to  claim 1 , wherein
 the first information comprises an information designating a sheet feed source of the image forming apparatus.   
     
     
         3 . The printing system according to  claim 2 , wherein
 the processor rewrites the first information so as to shorten a conveyance path from the sheet feed source to the first discharging section if the image apparatus comprises plural sheet feed sources.   
     
     
         4 . The printing system according to  claim 1 , wherein
 the second information designates one of a hole punch processing, a staple processing and a booklet processing as the post processing.   
     
     
         5 . The printing system according to  claim 1 , wherein
 the first information in the print data received by the reception interface is set by a user or set as a default.   
     
     
         6 . The printing system according to  claim 1 , wherein
 the second information in the print data received by the reception interface is set by a user.   
     
     
         7 . The printing system according to  claim 1 , wherein
 the memory, the reception interface, the processor and the transmission interface are arranged inside a computer which creates the print data.   
     
     
         8 . The printing system according to  claim 1 , wherein
 the memory, the reception interface, the processor and the transmission interface are arranged inside a computer which is capable of performing transmitting and receiving data to a computer which creates the print data.   
     
     
         9 . A method for a computer to rewrite print data, comprising:
 receiving a print data which comprises a first information designating a first discharging section which stacks image formed sheets in an image forming apparatus and a second information designating a post processing;   extracting the second information from the print data;   storing the print data in a memory if the post processing is designated in the second information;   rewriting the first information of the print data so that the first discharging section is designated and storing the rewritten print data in the memory if none of the post processing is designated in the second information; and   transmitting the print data stored in the memory to the image forming apparatus.   
     
     
         10 . The print data rewriting method according to  claim 9 , wherein
 the first information comprises an information designating a sheet feed source of the image forming apparatus.
