NVRAM PJL factory variables

To use these commands, you need some method to send PJL

commands to the printer, either with a software tool or by copying a

binary file that contains the commands from the host using a DOS

box. For example, from the DOS prompt:

copy /b filename lpt1

Here is an example of a file that uses one of the commands:

ESC%-12345X@PJL SET SERVICEMODE=HPBOISEID

@PJL ‘command’

@PJL RESET

Here is an example of using the NVRAMINIT command:

ESC%-12345X@PJL SET SERVICEMODE=HPBOISEID

@PJL NVRAMINIT

@PJL RESET

Note Set SERVICEMODE before trying to set the variable or you will not get

the desired result. Also reset the PJL and print a report to verify that

the SERVICEMODE status is cleared.

To create these files, you need an editor that can insert the ESC

character or is able to copy it in from a existing file. If a software tool

is used, simply send the same strings in the same order as given for

the example files.
