I did manage to get the printer going. I should have mentionned long
ago what the final problem was.
It turns out I was trying to print a pdf to a postscript printer. I
thought that pdf was a specialized form of postscript, the way inkscape
files are a specialized form of svg. Turns out that was completely
wrong.
The message I got from the printer was completely misleading.
Something about an invalid service ID. The service ID was valid; the
file I was sending to it was not.
Printing an actual postscript file worked just fine.
