I have been having similar with problems with my printer dropping pieces
of files on an HP Laserjet printer to my Sun 3/280 under OS 4.0.1.  After
some experimentation I have decided it is probably a tty driver problem.
A work around is to print a lot of spaces (~200 work nicely).  either at
the end of the file, or in another file in the queue right after the one
you want.  At least for me, the dropped charaters are only in the last
printout before the queue empties.  I have a call in to Sun, but they have
not gotten back to me (surprise surprise).

As for the dropping of escape characters, either use the -l option to lpr,
or write your own filter.
