HP Officejet 6000 will not print on mountain lion

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

Select "/var/log/cups/error_log" from the file list in the Console window. Then select the messages from the time of the last printing attempt. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.

If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.

When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

Please do not indiscriminately dump thousands of lines from the log into this discussion.

Or try resetting the print system (which will delete your printers):
