TROUBLESHOOTING AND MAINTENANCE
In this case, please install the machine printer driver again or copy BI-
DI.386 from the CD-ROM to the Windows/System directory. (NOTE:
BI-DI.386 on Disk 1 is not compressed.)
HP LaserJet series II, IID, IIP, IIP+, III, IIID or IIIP:
If Microsoft Windows
®
Printing System for above models are used, you
have to modify the “win.ini” file which is in the Windows directory to
turn the printer’s bi-directional function off.
We recommend you take a back-up before you modify the WIN.INI or
SYSTEM.INI, just in case.
Open the file “win.ini” by using the “Notepad” application. You can find
the following statement in the [spooler] section.
[spooler]
QP.LPT1 = wpsljqp.dll
To disable this function, put a semicolon at the start of the sentence as
follows;
[spooler]
;QP.LPT1 = wpsljqp.dll
Then, open the file “system.ini” by using the “Notepad” application. You
can find the following statement in the [386Enh] section.
[386Enh]
device=wpsljvpd.386
WPSLPT1=1
To disable this function, put a semicolon at the start of the sentences as
follows;
;device=wpsljvpd.386
;WPSLPT1=1
You must restart Windows
®
to make these modification effective.
The modification disables the printer status reporting on your PC,
however, you will be able to use the machine with no further problems.
