D Printer Commands Overview Most software applications 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 HP-GL/2 PJL PCL printer commands tell the printer which tasks to perform or which fonts to use. This appendix provides a quick reference for users who are already familiar with PCL command structure. Note Unless PCL 5e backward compatibility is required, HP recommends that PCL 6 printer drivers be used to take full advantage of all printer features. The PCL 5e printer driver in this printer is not backward compatible with older printers that use PCL 5e printer drivers. 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. 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 The table at the end of this appendix contains commonly used PCL 5e commands (page D-5). 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 CD (page 8). ENWW Printer Commands D-1
