Printer sharing control method and a system for implementing this method
View Patent ↗A computer ( 2 ) connected to a printer ( 1 ) stores a printer sharing control program ( 50 ) for creating print spool files and sending the print spool files to the printer in response to print requests received from a plurality of printer use programs ( 40 ). The printer sharing control program ( 50 ) generates an interrupt printing control function ( 56 ) for storing interrupt printing condition information set to each print request source, a temporary storage function ( 54 ) for temporarily storing the print spool files for distinguishing the print request sources, and a data processing function ( 52 ) for sending a priority print spool file to the printer based on said interrupt printing condition information.
1. A printer sharing control method for creating print spool files and sending the print spool files to a printer in response to print requests received from a plurality of printer use terminals, said method comprising:
an interrupt printing controlling step for storing interrupt printing condition information set to each print request source, wherein said interrupt printing condition information includes an interrupt pattern for providing timing of an interrupt printing to be made during a printing operation on a print request;
a temporary storing step for temporarily storing said print spool files created, in a way to distinguish the print request sources; and
data processing step for sending to said printer a print spool file to be printed with first priority, selected from the print spool files stored temporarily based on said interrupt printing condition information.
2. A printer sharing control system as defined in claim 1 , further comprising an error message conversion step for defining, for each terminal, a form of converting an error notice received from the printer into an error message to be sent to each print request source.
3. A printer sharing control system as defined in claim 1 , further comprising the step of adding information on a printer use terminal requesting prints when a print spool file is sent to the printer.
4. A printer sharing control method as defined in claim 1 , wherein said interrupt printing condition information includes a data structure having bit areas for providing said printer use terminals.
5. A printer sharing control method as defined in claim 4 , wherein said interrupt printing condition information includes a unit of interrupt for providing a proportion to be printed of all prints in an interrupting print request.
