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)

    I am not sure what you mean by setting up AirPrint, but have you tried deleting and re-adding the printers?

    You shouldn't need to add the vendor drivers if you are using AirPrint (unless you want to scan).  Also, I am not sure the Artisan 700 is AirPrint compatible. It's not listed here: And it shouldn't be necessary to add the printers over USB to see them from your phone. Perhaps the network isn't set up correctly, as you say.

    Since you are not worried about AirPrint for now, you could try deleting the /Library/Printers/hp, /Library/Printers/EPSON, and /Library/Caches/Epson folders. Then plug the printers in and let Software Update download the drivers. Then try printing a simple document from TextEdit.


    I am not sure what to suggest after this since you have already reset the printing system.

    How are the printers added? USB? What app are you printing from? Happy to try to help, but I am out of ideas.

    I believe I'm seeing this same issue but on 10.6.8.  I have gotten the self test page to print (again after trying guttenprint) but still failing to print actual documents.


    How does one go about re-installing the CUPS driver?
