PJL overview Printer Job Language (PJL) is an integral part of configuration, in addition to the standard Printer Command Language (PCL). With standard cabling, PJL allows the printer to perform functions such as: z Two-way communication with the host computer through a bidirectional parallel or LIO connection. The printer can tell the host such things as the control panel status. z Isolation of print environment settings from one print job to the next. For example, if a print job is sent to the printer in landscape mode, the subsequent print jobs print in landscape only if they are formatted for landscape printing.
Note PJL commands can be sent to the printer only from a DOS command prompt and through a parallel cable. DOS applications are not supported over a USB interface. ENWW Formatter system 57
