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. </pre> </blockquote> <pre wrap=""> Do you have a firewall running? Try using system-config-securitylevel to add 631:tcp to the list of open ports (on the machine with the printers attached). </pre> <blockquote type="cite"> <pre wrap="">[...] Please help.
