I transferred by Lexmark E234 laser printer from my Opteron machine to the MacMini Server (USB). It was trivial to print to it from the MacMini.
But how to get the G5 running 10.4.11 to print to it? It didn't show up in the browser. Trying to add the printer to the G5 manually via the Samba trick (option click on Add printer and so forth) always failed.
It turns out, you've got to enable sharing of it in CUPS on the Mini first.
http://localhost:631/admin to get to the CUPS interface. If you click "Share printers connected to this system", it doesn't stick. You've got to read this page - http://www.cups.org/...-1.4/sharing.html - then run the "cupsctl --share-printers" command from a terminal (and may need Admin privileges). After running that, the checkmark will stick, and the shared printer will magically show up in 10.4.11.
Clear as mud.
I hope it sticks through reboots... :-)
Cheers,
Scott.
