摘要 |
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.
