How suppress print dialog box

I sure would appreciate receiving a Preference file that already suppresses the print dialog box. I am printing from a g3 beige under OS 9.1 to an Apple Laserwriter 4/600 PS, and I am using the Chooser choice Laserwriter 8 to choose from. Actually, it would probably be enough to just know WHICH preference file I need to replace - its driving me nuts switching from the application I'm printing from over to the Finder in order to press Enter - every time I send a document to the printer. Because my other hard drive supresses the dialog box, I just can't do it on the hard drive I use all the time. Thanks
