TROUBLESHOOTING AND ROUTINE MAINTENANCE
HP LaserJet series II, IID, IIP, IIP+, III, IIID or IIIP:
If Microsoft Windows
®
Printing System is used for the above models, you
must modify the “win.ini” file in the Windows
®
directory to turn the
machine’s bi-directional function off.
We recommend that you do a back-up before you modify the WIN.INI or
SYSTEM.INI files, just in case.
Open the “win.ini” file using the “Notepad” application. Look for the
following statement in the [spooler] section:
[spooler]
QP.LPT1 = wpsljqp.dll
Then disable this function, by adding a semicolon at the beginning of the
above sentence as follows:
[spooler]
;QP.LPT1 = wpsljqp.dll
Then, open the “system.ini” file using the “Notepad” application. Look
for the following statement in the [386Enh] section:
[386Enh]
device=wpsljvpd.386
:
:
WPSLPT1=1
Then disable this function, by adding a semicolon at the beginning of the
above sentences as follows:
;device=wpsljvpd.386
:
:
;WPSLPT1=1
You must restart Windows
®
to make these modifications effective.
These modifications disable the printer status reporting on your PC;
however, you will be able to use the machine without further problems.
