I have used various flavors of nroff on various machines, and have never
seen this happen.  Are you sure that there is not something funny in
your local configuration or mm macro file.

This is just a guess, but the HP DeskJet has two output modes: text scale
which gives you 66 lines/page, and unscaled which gives you 6 lines/inch, 
but slightly fewer than 66 lines (63?) due to top and bottom margins.  If
your printer suddenly started using unscaled output (set by a dip switch
or escape sequence) and nroff were sending 66 lines (a few of which fall
onto the next page), then a formfeed, it would explain what you are 
seeing.  Like I said, this is just a guess, since I don't know where the
formfeed would be coming from.
