On latest drivers from apple and HP.com/support this april 2010: The drivers send a generic signal into the printer to pause after each print. This can really get aggravating. I found a fix for it however, remove the generic drivers from apple for HP, remove your installed driver from HP. Go to hp.com/support download newest driver (currently 1 April 2010) Install driver as normal Follow these steps: Install new driver by double clicking it dur System Preferences --> Print & Fax Double click on your desired HP printer, this will open the printer window for that printer Click on the right icon "Printer Setup" Go to "Utility" and click the button in there "Open Printer Utility," this will open your default internet browser and log you into the printer (be sure it's connected via USB) At the top, click on "Settings" Then select "System Setup" Turn "Auto Continue" option to "On" Then click "Apply" button at bottom right. And you're set. Not sure why the latest drivers screw with this.
