According to a DEC salesman I talked to, the printer can only be hooked
up to DECnet, so if you want to use TCP/IP with it, you'll need an ULTRIX
machine as a gateway.  He also told me that the software that runs on the
ULTRIX machine doesn't support the UNIX LPD protocol, so you'll have to
implement DEC's proprietary printer protocol on your TCP/IP machines.

That sounds like a PostScript programming problem rather than a problem
with the printer itself.  I had that problem myself with another printer,
and solved it by doing appropriate rounding of the coordinate values in
the device coordinate space.
