Note 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 Set SERVICEMODE before trying to set the variable or you will not get the desired result. Also reset the PJL to be sure 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. EN Service mode functions 185
