Appendix D Printer Commands 322 HP-GL/2 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 language and enter HP-GL/2 mode, which can be done by sending the printer PCL code. Some software applications switch languages through their drivers. PJL HP's Printer Job Language (PJL) provides control above PCL 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 may be used to change printer default settings. Note This appendix includes: z Understanding PCL Printer Command Syntax z Selecting PCL Fonts z Common PCL Printer Commands The table at the end of this appendix contains commonly used PCL 5e commands (page 327). For a complete listing and explanation of how to use PCL, HP-GL/2, and PJL commands, order the PCL 5/PJL Technical Reference Documentation Package (page 36).
