PROBLEM TO BE SOLVED: To securely speed up acquiring printing data from transmission data in printing process. SOLUTION: When a print server 12 receives a PDL, a job ID detecting part 32 detects a job ID. When no job ID is added, job ID is issued by a job ID issuing part 34 and the PDL and image data outputted from an RIP part 30 are stored into a storage device 46 on the basis of the job ID. When any job ID is detected, a job retrieval par 48 retrieves data based on the job ID and reads the previous PDL. A page image selecting part 50 compares the PDL of this time with the previous PDL for every page and conducts RIP processing only for the compiled page by using the PDL of this time. Thus, the time required for outputting image data is shortened. |
