If you upgraded from an older version of mac OSX to Lion you may need to uninstall the software for the printer using the 'scrubber' method.
Go to Applications/Hewlett Packard/ click on HP Uninstaller
Click on Continue
Highlight your device on the left pane
Hold the Ctrl, Opt and Cmd keys and click on Uninstall <<<< Scrubber Option
There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled)
Click Continue and let it finish
Restart your Mac
Now, run a Software Update.
Finally, reset the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
Hope this helps!
