Printing Problems (2nd request)

[Joseph McCrary]

Please help. If I cannot fix this printing problem, I will have to 
abandon Linux for the hated world of Windoze!!!

Two weeks ago, I no longer could send a document to either printer. I've 
got two printers connected, both of which used to work fine. One is a 
Canon S600 connected to a USB port. The other is a HP LJ 6MP connected 
through my local network. Both worked fine previously.

Whenever I try to print from a program (e.g., Firefox), the only printer 
available is the PostScript default. Previously, both printers were 
listed, with the HP as the default printer.

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

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

I'm running Core 3, and have done all of the updates. I downloaded and 
installed the latest version of CUPS (1.1.22). That did not help.

Here are the last few lines from cups.conf:

# Encryption: whether or not to use encryption; this depends on having
# the OpenSSL library linked into the CUPS library and scheduler.
#
# Possible values:
#
#     Always       - Always use encryption (SSL)
#     Never        - Never use encryption
#     Required     - Use TLS encryption upgrade
#     IfRequested  - Use encryption if the server requests it
#
# The default value is "IfRequested".
