I've had a problem with this for years.

Confusingly, ps-paper-type does seem to behave as you describe. But if 
that's the case, how to actually set the page size of postscript output? 
(and for clarity, by page size, I'm referring to the dimensions of the 
white rectangle that sits behind the printed text, the digital analogue 
of the bleached tree carcass that runs through the machine in the corner 
of the office).
