About a week ago, I installed FC5, subsequently defined a printer queue, and the printer (hp deskjet 5550) worked fine. I use a router to network two computers. FC5 is only on the "main" computer. So I set about to share the filesystem with the second computer, still running FC4. On the FC5 computer, I went to System->Administration->Network to get "Network Configuration" and set up the proper host names recognized by the router. I discovered that the FC5 computer was listed as localhost.localdomain at 127.0.0.1. I could have sworn that during the installation of FC5, I entered its correct name and IP address and don't know where 127.0.0.1 came from. Anyway, I made the necessary changes and additions in Network Configuration:

localhost1.localdomain at 192.168.1.100 (running FC5)
localhost2.localdomain at 192.168.1.200 (running FC4)

That part was successful. When I boot localhost2, I now can mount the filesystem from the hard drive on localhost1 onto localhost2.

But now the printer, locally connected to localhost1, stopped working! I looked at cupsd.conf and saw that mysterious address 127.0.0.1. Assuming that this was why the printer stopped working, I changed those values to 192.168.1.100. I also deleted the print queue and created a new one. But I just can't get the printer working. When attempting to print the test page at the end to the queue-creation process, I get "server-error-service-unavailable."

Any ideas how to fix things? Thanks so much.

127.0.0.1 is the loopback address and is used for all sorts of thing on the local machine and it is absolutely essential that it is defined. This is true for Linux, Windows, whatever.

Check your hosts file (should be in /etc), and make sure it has a line like

127.0.0.1 localhost host localhost.localdomain

otherwise your networking will be stuffed
