Note Printer Utility Examples The following three examples demonstrate the kind of PJL jobs used by Printer Utilities: • Jobs that request information and perform printer setup • Jobs that request information, set features, and print existing files • Jobs that monitor printing status Jobs that Request Information and Perform Print Setup The following example demonstrates a job setup utility that first asks for printer information, then sets default features to a desired state. This application functions like a remote control panel. This type of utility enables users to select PJL features before printing from another application that cannot select PJL features. In this example, the DEFAULT command is used instead of the SET command, so that changes apply to all future print jobs. Since this application uses the DEFAULT command, it changes the User Default Environment and control panel settings. In multi-user situations, it should be used only by printer administrators to avoid unexpected results by other users.
