No Printing After Removing Router

Here's my situation: I have a current FC1 setup and a static IP, and added a router to update a couple of extra (older) machines I had with Fedora. I configured the router with the network numbers associated with my static IP, and this machine was then set as DHCP. The updates were done, and the other boxes were disconnected. I have taken the router off and reconnected the incoming line back to my original FC1 box. I reconfig'd this box with the network configuration tool to be exactly as it was before the temporary router add-on. Everything seems to be back to normal with one exception: I can't print anything now!

So I went into RedHat->System Settings->Printing and checked all the settings. It's a locally-connected HP LaserJet 6L and everything there looks normal to me:

Queue Type is Locally-connected, /dev/lp0
Printer driver is HP LaserJet 6L

I've tried /sbin/service cups start and that gets me a [OK] as a response.

I've tried rebooting.

I've google'd for the errors that I'm getting and found a note about a potential conflict with symbolic links, but wasn't clear if that was my problem.

Here are the errors that I'm seeing:

Say I want to print a file that I saved from mozilla, here is the output:

[clint@localhost clint]$ lpr mozilla.ps
lpr: error - scheduler not responding!

When I try to print a test page I get this error:

There was a problem sending CUPS test page
to 'printer' queue:

lpr: unable to print file: server-error-service-unavailable

I'm fairly sure that there is some sort of conflict that has happened when I removed the router and attempted to return this machine back to its prior state, but I simply am at a total loss about what to do now.

I sure could use help for what to do to fix this printing!

Thanks,
Clint
