Printing from RedHat 9 to 10.3.2, why doesn't it work?

[michaelsanford]

Current configuration:
• 10.3.2 is on 192.168.0.5 (also called nimbus.local)
• RedHat 9 is on 192.168.0.7 (also called trogdor.local)
• Epson Stylus Colour 777(i) attached via USB to Panther iMac, and turned on
• All networked via a D-Link DI-604 router with static DHCP addressing.

I have enabled:
• Mac OS X Printer Sharing (in the Sharing pane)
• Added a CUPS printer on my RH9 machine to 192.168.0.5 as an Epson Stylus Color 777. I assume the "path" field refers to a local spool path (and not a remote unix socket on my iMac).
• Checked that ipp (port 631) is open on my Mac (and that cupsd is running).

When I try to print a test page from my RH9 machine, I get a server not responding message.

Interestingly in netinfo manager, there are no entries in either the "/services" or "/printers" nodes.

How can I, and why can't I currently print over my network?

Ok, for some magical reason it works now...
