HP PSC 1200 Series Printer - Error Connecting To The CUPS Server

[vincent]

Please Help.

My HP printer has been working perfectly on 8.04.1 until this morning.

On start-up & trying to print anything at all, the print manager shows a 
job in progress but nothing happens - I've left it running for two hours 
& still nothing.

The error report says "There was an error connecting to the CUPS server"

Unfortunately, not being too knowledgeable with linux, it doesn't mean 
much to me.

This is a dual boot machine & on opening xp, the printer works fine, so 
I've established at least, that the printer is OK.

I'm running my business off this machine, so any help or pointing me in 
the right direction would really be appreciated.
