There was a day when nothing but Apple and PostScript printers worked with Apple Macintosh computers. Part of the OS revisions was to give hooks for the printer makers to develop drivers.
Sadly, I have no firm answers but you should hunt up 8.5.1 if that's all it will take to print...
I am thinking of buying a new printer for my Bondi Blue Apple iMac. My OS is Mac 8.5 and I can't seem to find an affordable printer that works with 8.5. At Wal-Mart they have a Lexmark printer that works with Mac OS 8.6. Would that printer work on 8.5? There is a cheap Epson printer that works with Mac OS 8.5.1 Will it work with 8.5? Does anybody know of a printer that would work with OS 8.5 that cost between $20-$65?
