how about replacing dpkg -s lprng with
grep -A1 '^Package: lpr$' /var/lib/dpkg/status
and grep -e "^Status: install ok installed" with
grep -q -e "^Status: install ok installed"
(helps in suppressing unnecessary output)
comparison times:
dpkg -s lpr 5.71s user 0.37s system 35% cpu 17.182 total
grep -A1 '^Package: lpr$' /var/lib/dpkg/status 0.00s user 0.04s system 155% cpu 0.026
