BTW, which version of Debian are you using? Usually restarting CUPS service is enough to reinstate a given printer queue. If you're having regular problems with printing it can be useful to examine the CUPS error log, and you may want to consider putting CUPS in to debug mode for additional logging verbosity.
Code:
sudo cupsctl --debug-logging
It can be turned off again with
Code:
sudo cupsctl --no-debug-logging
