As noted on the Mac Photoshop User to User forums (see original thread) there seems to be a reproducible issue with the Photoshop CS2 (9.0.2) update when installed on Mac systems running 10.3.9. The problem seems to cause an immediate crash when trying to print from Photoshop 9.0.2.
According to Dave Howe from Photoshop Q&E, they are able to reproduce the problem and engineering is looking into the problem. Adobe may be pulling the Mac 9.0.2 Update to fix the issue with system 10.3.x. There does not appear to be any issues when using Photoshop 9.0.2 to print under 10.4.x.
Note: if you have 10.3.x you may need to re-install Photoshop CS2 (9.0.0) and do the 9.0.1 update until the issue is resolved. The 9.0.2 update is still only available via Adobe Updater and is not yet posted as a download.
The Windows version of the 9.0.2 updater does not seem to have any problems reported as yet.
