Am using 12.1 (64bit). Trying to connect to a HP Photosmart Premium C309g printer using a wireless connection.
Setting it up using a USB connection works properly.
Following HPs instructions, I connect a USB cable and add a printer using the 802.11 selection. I change the printer name to avoid conflict with the existing printer configuration. All seems to go well until the finish button is pressed and I then get an error "user ls being added to lp" and the printer is not added.
I can add it using cups, and it works using cups test printer function. But is not available as a selection from any application.
