Q: What does the 7.5.2 Printing Update 1.1 update? Why do I need it?

A: This extension fixes a printing problem that may occur on Power Macintosh 7200, 7500, 8500, and 9500 computers using System 7.5.2. Without this fix, your computer may freeze if you attempt to print on a network-based printer that is already busy, and it may be necessary to restart your computer.

The update contains a new version of the LaserWriter driver (8.3.2) and also a fix to serial DMA. The changes fix the ATP and PAP networking protocol layers.

The updates you will need are:

7.5.2 Printing Update 1.1 and Open Transport 1.0.8.

An updated version of the PAP.WrkStation.o library will be distributed on a future version of the Mac OS SDK and developers who have licensed the library will be notified via email when the new library is available.
