Antidote to the A4 printing error problem

Frank Gravier gets a gold star for discovering the antidote to the A4 tray error printing problem. When you encounter that error and there is no staff at the IT Help Desk, press 7 (for plain letter) and then enter (next to the number 4 and a left arrow), and the job will print out. It may not stop the A4 error from occurring but at least it doesn't hold up everyone else's print job.
