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.

HP LaserJet 4 Plus:
