Just set up cupsd on centos 6.4 to share a USB printer on my local network (new to cups, but not centos). Test pages print fine from the local machine, and have all appearances of success when printed from a remote machine.
The logs indicate the job completes with no errors with the log level turned up to 'debug'. Unfortunately, the printer is not spitting out a printed page - it just sits there like a rock... at least it doesn't say "PC LOAD LETTER".
I'm also finding the cups documentation to be woefully lacking... any ideas on what/how to troubleshoot?
