I suspect it's just that the hardware margins are off by a little
bit on that printer.  There are two things that might help.  One
is the "setmargins" operator that should be documented in your
printer documentation somewhere (it permanently adjusts the hardware
margins).  The other is the *DeviceAdjustMatrix entry in the PPD
file, which is intended to help solve problems caused by slight
differences from one marking engines engine to another (within the
same product).  Some of them actually distort the scale slightly,
too.
