Abstract
A printing system wherein a first print driver utilizes an Intelligent Printer Data Stream (IPDS) to send a first job at a first font resolution to a printer and a second job at a second font resolution or a second job utilizing a non-IPDS data stream to the printer. A second print driver also utilizing the IPDS data stream is connected to the same printer for sending a third job. By sending a "Manage IPDS Dialog (MID)" IPDS command to the printer upon conclusion of the first job, the printer is enabled to switch immediately to the second job. The printer is enabled to switch between the first and second print drivers by use of the MID command at the conclusion of a print job.
