[TriLUG] print queues work locally, but not over the network

[Steve Litt]

Hi all,

My computer has an HP4050 hooked to its parallel port. Most printers in the 
house run Mandriva 2006 and access my printer via the network. I upgraded my 
computer to Mandriva 2007, and all of a sudden none of the other computers 
can print to my printer. It (in all its various configurations such as lp, 
lp_dark, lp_duplex etc) shows up on all the other Mandriva machines, but when 
you print to it on those printers it "vanishes into thin air". Nothing prints 
on my printer, and the lpq -P lp_dark command says nothing's queued on their 
computer or on mine. I can't figure out what happened to the print job. The 
same print job works perfectly if I sftp the file to my computer and then 
print it from my computer.

The cupsd daemon is running on all the computers, and lp_dark (and the others) 
show up at http://localhost:631 on all the computers.

This seemed to start when I upgraded my computer from Mandriva 2006 to 
Mandriva 2007.

What are some of the steps I'd take to troubleshoot this problem? My wife and 
kids have started a fire under a 1000 gallon pot, and I'm scared I'll get 
boiled if I don't get the family's printers printing.

Thanks
