All my printer interface scripts keep a count of blank lines,
then send that number of LF characters when they see a non-blank
so no trailing blank lines are printed at the end of the job.  At
the end of the job with HP printers, the script sends <ESC>E
which prints anything remaining in the printer's buffer, and with
non-HP printers, it sends a FF (ctrl-L) character to eject the
last page.

This is pretty simple in python or perl, something like

blanks = 0
for line in sys.stdin:
    line = line.rstrip()
    if not line:
        blanks += 1
        continue
    if blanks:
        print '\n' * blanks
        blanks = 0
    print line

Perl is similar with lots of modem noise.
