The problem was that I was trying to use a standard DB-25/DB-9 serial adapter
rather than a special adapter from HP. I got the correct pin layout for the
adapter from <matthew.hofener@camp.org>:

        Sun (DB25M) HP (DB9M)
        =========== =========
             2 ------------ 3
             3 ------------ 2
             5 -+
                |
             6 -+---------- 6
             7 ------------ 5
             8 ------------ 1

and the printer prints.
