Hiding printer dialogs

Hi All,
I hope I’m posting the question to correct list. We have the requirement of printing on post script file printer from flash application. Now during printing two dialogs pops up, one is printer dialog to select printer and another is file name input dialog to take the ps file name. How can we hide these dialogs? Can we accomplish this from user space API or we have to write a customized printer driver? Any help in this direction would be appreciated.
