Yes, indeed.  First, you have to realize that a Printing Grafport reflects
(in portRect) the page size you set up in Page Setup.  It may, or may not, even
HAVE a bitmap (much less a bitmap.bounds -- in the Printing Grafports I set up
for spooling, bitmap.bounds is (0,0,0,0)).  Yes, you should set the clipRect to
portRect, and the visRgn to clipRgn.  However... if the printing area is not
right, try setting the desired size in your print record and then do a
Validate on it.  What comes back should be somehow related to the best
approximation the printer can give you.
