No. There are PostScript-Printers out there - but your off-the-shelf InkJet
isn't, and that's the reason why there usually has to be some sort of
driver in-between. Which is either GS or, in case of PDF, the acrobat-* or
any other PDF-printer-emulator. 

maybe you can go down the rocky road of automation here, remote-controlling
acrobat reader. But I doubt that it wouldn't at least flash up with its
window for as long as the printing lasts.
