Believe it or not, this is an arithmetic error in the Postscript interpreter,
apparently caused by some sort of compiler bug.  Talk to HP and describe the
problem.  We found this same symptom -- also in a dvips-generated file -- and
traced it to just plain wrong arithmetic.  HP promptly sent us a new Postscript
SIMM, without charge I think, and the problem went away.  (You have to send
the old SIMM back after receiving the new one.)
