Download Google Chrome Version 18.xx.xx.xx and you can use flags to turn OFF the printer dialog

--kiosk-noprint

Something of that fashion I can't quite remember off the top of my head but google will help on that. That will allow the dialog to stay out of the way when you select whatever you want to print.
