Well.. it turns out it is the printer - I had them hook up a LaserJet 4
and it works fine. To get the 1320 to work consistenly, I had to
explicity change the text box's Fill from the default white to No Fill.
I also found that for the single frame on the page, I had to explicity
set its Fill to No Fill, its Style to Clear, and apply these to the
Paragraph. I have absolutely NO explanation why these changes allow the
HP 1320 to avoid priting borders that are set to No Line.
