The Resource Manager for your machine’s Brother printer drivers may not work if the printer drivers for the above laser printers models are installed after the installation of your machine’s Brother printer drivers.

In this case, please install your machine’s Brother printer driver again or copy BI-DI.386 from the CD-ROM to the Windows/System directory.

(NOTE: BI-DI.386 on the CD-ROM is not compressed.)

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]
