C Printer commands Note Overview Most programs do not require you to enter printer commands. See your computer and software documentation to find the method for entering printer commands, if needed. PCL 6 and PCL 5e HP-GL/2 PJL PCL 6 and PCL 5e printer commands tell the printer which tasks to perform or which fonts to use. This section provides a quick reference for users who are already familiar with PCL 6 and PCL 5e command structure. The printer has the ability to print vector graphics using the HP-GL/2 graphics language. Printing in the HP-GL/2 language requires that the printer leave PCL 5e language and enter HP-GL/2 mode, which can be done by sending the printer PCL 5e code. Some programs switch languages through their drivers. HP's Printer Job Language (PJL) provides control above PCL 5e and other printer languages. The four major functions provided by PJL are: printer language switching, job separation, printer configuration, and status readback from the printer. PJL commands can be used to change printer default settings. The table at the end of this section contains commonly used PCL 5e commands. (See "Common PCL 6 and PCL 5e printer commands" on page 179.) For a complete listing and explanation of how to use PCL 5e, HP-GL/2, and PJL commands, see the HP PCL/PJL Reference Set, available on CD-ROM (HP part number 5961-0975). ENWW Overview 175
