printing errors HELP! unable to send printer command!
Using a mid 2007 imac running lion 10.7.3. Both printers, HP laserjet p1606dn and Epson artisian 700 worked fine until I tried to setup airprint (couldn't figure that out). Now I can't print anything, not even a test page, from either printer. I receive a print error- "Unable to send printer command! Unsupported document-format "application/vnd.cups-command". I can scan from the Epson without a problem. I can run utility tasks, clean print heads, run print head alignment etc. but i can't print, HELP please.
iMac, Mac OS X (10.7.3)
