Hello Maceymoo,
I would uninstall the print driver and reinstall with the latest Xerox print driver. You can find the latest drivers HERE.
I can print emails fine, however when I go to print letters in comes up with the following;
Error - undefined
Error Code - 11-1412
Offending Command - JL
Stack
Anyone have a clue what this is, Xerox do not have any ideas!!
