Appendix D Printer commands 208 Note PCL 5e PCL 5e printer commands tell the printer which tasks to perform or which fonts to use. This appendix provides a quick reference for users familiar with PCL 5e command structure. 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. 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 5e language and enter HP-GL/2 mode, which can be done by sending the printer PCL 5e code. Some software applications change languages through their drivers. PJL 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 changing, job separation, printer configuration, and status readback from the printer. PJL commands may be used to change printer default settings. Overview

Appendix D
Printer commands
208
Overview
PCL 5e
PCL 5e printer commands tell the printer which tasks to perform or which fonts to use. This appendix provides
a quick reference for users familiar with PCL 5e 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.
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 5e language and enter HP-GL/2 mode, which can be
done by sending the printer PCL 5e code. Some software applications change languages through their drivers.
PJL
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 changing, job separation, printer configuration, and status
readback from the printer. PJL commands may be used to change printer default settings.
