This is for printing.  Do you know of a better way to print
something without first displaying it?  (Maybe applescript?)

The Carbon framework has APIs for printing. You would have to output things on that end (i.e., implemented in C) and then you can call the standard print dialogs that will handle everything from outputting to PDF, choosing a printer and using the right driver, choosing a layout for the pages, etc. That would be the correct way, and everything else is more or less a hack. It probably not worth implementing in Carbon, given that the Cocoa port is in the works.

That said, "lpr" should work for PS, PDF, plain text or standard image files even if the default printer is not PostScript capable (from OS X 10.4). So that's what I would try.

You can also print via AppleScript using the Preview application (it can bring up the print dialog directly), and that would work for PostScript files as well. But that's relatively hack-y...
