If a print job is designated to interrupt print, processing of any print job currently being processed is interrupted, print processing of the instructed print job is immediately performed and resumption of the interrupted print job is automatically performed afterward. Further, if an interrupt print occurs, the sending source of the interrupted print jobs (host computers, etc.) are notified that an interrupt occurred.

Print control apparatus, print control method, memory medium for storing print control program, and print control program

A print job can be identified without the print data of the print job being analyzed, and print data for a print job that is selected, e.g., print data stored in an input buffer, can be invalidated. In addition, the cancellation of a print job can be designated in real time. To achieve the above object, a host computer and a printer are interconnected via a communication medium. The host computer comprises job packet generation means for adding a header to print data to form a packet for each print job that is generated. The printer comprises job detection and registration means for detecting the start and end of a print job in accordance with the contents of the header of a packet received from the host computer, and for registering the print job in a database.
