CHAPTER 5 PJL - 5
1.2. In Case of Using PJL with a Non-PJL Printer
Our recent printer models support PJL, however, earlier models do not . If the PJL commands are sent to a
non-PJL printer, the printer acts as follows;
1.2.1. PCL jobs
For a PCL printer which does not support the PJL language, the PJL command is printed as ASCII text until
initial PCL printer reset command (E) is received. After receiving the PCL reset command, the
printer ejects the page and proceeds with the PCL print job on a new page.
The print job is possibly followed by more printed PJL commands.
Without the PCL reset command, the PJL commands are printed as ASCII text on the same page as the PCL
print job.
1.2.2. Postscript jobs
For Postscript printers, when the printer receives a PJL command, a Postscript error is reported. The
Postscript job is discarded.
1.2.3. Other printer languages
According to the active emulation, the PJL command is understood differently. To avoid the problem, you
should not use PJL commands on any non-PJL printer.
