Older colour laser printers are inadequate for photo printing -- capable enough for charts, line drawings, paint art etc. Modern printers (last six years, possibly older) can reproduce photos but may be expensive.
The reason I assembled the instructions at http://www.vintagema...m/osxprint.html was that I needed to print photos from older Macs using a cheap printer. Owing to the rapid development of Mac OS X, i decided to leave the instructions as a successful experiment.
tanuki65: If you can print an LPD test page from local host (ie the Mac running the server), I'd look at firewall problems. Check the firewall logs and settings. The LPD port (TCP 515) would need to be open to your old Macs and other test devices.
