Issue
All Macintosh computers, including PowerBook computers, have a compatibility issue with Personal LaserWriter SC driver version 7.0.1 (included with System software 7.1.1 and 7.5) or earlier versions.
When printing from a Macintosh computer using System Software 7.5.2 or newer to a LaserWriter IIsc or Personal LaserWriter SC, the line layout is very poor and definitely not "what you see is what you get" (WYSIWYG).
Solution
- for System Software 6-7.5.1, use Personal LaserWriter SC 7.0.1
- for System Software 7.5.2-7.6.1 use LaserWriter IIsc GX
- for Mac OS 8 use Personal LaserWriter SC 7.0.1
To avoid formatting problems, use the LaserWriter IIsc GX driver with System Software 7.5.2-7.6.1.
The Personal LaserWriter SC and LaserWriter IIsc are untested and unsupported under Mac OS 8. If you are going to attempt to print to one of these printers, Apple suggests trying the Personal LaserWriter SC driver version 7.0.1 (available from Apple Software Updates). However, you may experience some formatting problems with some applications. The LaserWriter IIsc GX driver is not compatible with OS 8.x
Notes
1. With most new CPUs you will need to turn the printer on after the computer finishes powering up (that is, the Finder has finished loading)
2. With the Personal LaserWriter SC driver you will have to click on the blank area on the right where a printer name or SCSI ID would normally show up in order to avoid "printer not found" errors.
3. Like any other SCSI device, be certain the printer has a unique ID and is properly terminated.
4. The QuickDraw GX printer driver is bundled with QuickDraw GX--it is not posted to online services separately. To download this driver from online services you must download all of QuickDraw GX.
