The Resource Manager for MFC 4550 plus may not work if the printer driver for the
above models are installed after the installation of the MFC 4550 plus printer driver.
In this case, please install the MFC 4550 plus printer driver again or copy
BI-DI.386 from the Brother CD-ROM to the Windows®/System directory. (NOTE:

HP LaserJet series II, IID, IIP, IIP+, III, HID or HIP:
If Microsoft Windows® Printing System for above models are used, you have to modify
the ‘Svin.ini” file which is in the Windows® directory to turn the printer’s bi-directional
function off.
We recommend that you perform a backup 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.LPTl = wpsljqp.dll
To disable this function, put a semicolon at the head of above sentence as follows;
[spooler]
iQP.LPTl = 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
