Is there a way to have a web-based app (using Google Chrome) auto-print? [closed]

http://serverfault.com – I am building a web-based application. My users will utilize Google Chrome exclusively. I want to have auto-print when certain pages are opened without the typical Google Chrome print dialogue. Is this possible? (Note that on other pages I want to access the print dialogue to provide customer with choice of printer and print options). (HowTos)
