Did you know you can print a file from within the Finder, without opening it first? Well, you can… at least in Tiger (Not sure about Panther). Simply right-click (or control-click) on any file and select Print from the contextual menu. It’s that easy.
Another method would be to create a Desktop Printer, which allows you to drag a file to a printer icon on your desktop to print it.
Aah, ‘Desktop Printers’..reminds me of the good old OS 9 Days. :)
For a lot of files, you can also just press (APPLE)-P, while in Finder.
