No need to pipe to gs manually. The spooler uses CUPS which invokes GS (unless printing to a PostScript printer).

And yes, you can do this from the terminal. E.g. under Gnome you would use gtklp instead of plain lp, which even brings up a nice dialog IIRC.

I am especially interested in frameworks for printing, and wrappers that provide a canvas interface to a printer.  I found a copy of Sophie 1.04 that has some code in Sophie-Printing.  Is there anything else I should study?
