2. Description of the Related Art
In general, a printing apparatus, such as a copying machine, a printer, and a facsimile machine, performs so-called paged management, by which print data is stored per page in a hard disk or a work memory, so that print data is printed out page by page.
Assume that a print unit (hereinafter, referred to as a job), such as a whole set of document data, is inputted into such a printing apparatus adopting the paged management via a communication line or the like. Then, if the job includes paged data of more than certain manageable pages (for example, 999 pages) determined by processing ability of an MPU or the like, the job is divided into a plurality of jobs, which are subjected to input processing and printed out successively.
In a case where the print processing of a job A preceding to a job B has not ended yet when the input processing of the job B is started, or a case where the input processing of the job B is started after the print processing of the preceding job A ended but during a print-inhibiting time period for inhibiting the print processing of a new job to accept a request of interruption printing from a user who directly manipulates the printing apparatus to make a copy or the like, the printing apparatus is controlled to start the print processing of the job B not immediately, but after the input processing of the job B ends (referred to as the prior art P).
The following description will describe a copying machine as an example of a printing apparatus according to the prior art P. FIG. 7 is a time chart explaining an operation when two jobs A and B are inputted in succession. In the drawing, t11, t12, and the like denote instants on the time axis.
Initially, input processing of the job A is started by a central processing unit (CPU) of the copying machine (t11). This input processing continues until the input processing for the entire paged data of the job A ends (t13). As a result of this input processing, the paged data included in the job A is successively written into a certain work memory area.
Meanwhile, print processing of the job A is started when any of paged data is written into a certain limited work memory area by the input processing of the job A, (t12). This print processing continues until the entire paged data of the job A is printed out. The print processing of
