Abstract

Concurrent IPDS and non-IPDS print processing is provided. Because an IPDS print session may not usually be interrupted, non-IPDS print data is received through a separate, non-IPDS channel in the printer control unit. The non-IPDS data is rasterized (“ripped”) using spare processing cycles and stored in a rip spool. At an appropriate time, such as when fully rasterized, an interrupt request may be submitted to the IPDS host then controlling the printer. When the IPDS host relinquishes control of the printer, such as when the IPDS print job has been completed, the rasterized non-IPDS print data may be de-spooled to the print engine and printed.
