The problem is related to some known printing issues with PCI-based Macintosh computers. The problems are resolved with some new AppleTalk PAP/ATP fixes included in the LaserWriter 8.3.2 printer driver, and the 7.5.2 Printing Fix extension. If System 7.5.2 Update 2.0 is installed, the Printing Fix extension is no longer needed.
In the QuickDraw GX environment, the LaserWriter GX driver has not been revised to include the AppleTalk PAP/ATP fixes. This is the reason that the LaserWriter GX driver (J-1.1.2) does not work. The QuickDraw GX engineering team scheduled the fixes to be rolled into QuickDraw GX v1.2.
One possible workaround to this issue if the customer wants to use QuickDraw GX is to use QuickDraw GX Helper. This allows you to use the LaserWriter J1-8.3.2 driver within QuickDraw GX. For an explanation of how to use QuickDraw GX Helper, please see the following Tech Info Library article:
