If a printer supports custom paper sizes, in particular ones which are
much larger than any that correspond to a standard paper, the printout
is clipped.

I have attached a short piece of code which demonstrates the problem. If
the code is executed with jdk 1.2.2 I get the expected 66 inches of paper,
however if it is executed with jdk 1.3 I get only 41 1/2 inches of paper
even if I set the default page for the printer to the desired size (12"x66").

At this point I'm not sure how to proceed. We do not want to revert to
1.2.2 because of the "auto-scroll" bug and other performance reasons, but
we need to support large format printers.

The large format printer we are using is a HP DesignJet 2500CP.
Driver: hpltdrv1.dll v4.00

Also, there is nothing special about this particular size. It just happens
to correspond to 100 ft at 1/20 scale with some extra room for headers,
footers, and margins.
