This is the /etc/printcap I once used: (now I have a DecLaser 3500)
lp0|local laser printer:\
       :lp=/dev/cuaa2:\
       :rw:\
       :of=/usr/local/bin/lpof:\
       :fc#0000374:fs#0000003:br#38400:\
       :xc#0:xs#0040040:sf:sb:br#38400:\
       :mx#0:sd=/var/spool/output/lpd:lf=/var/log/lpd-errs:

/usr/local/bin/lpof was a C program which was a hack and quite
inadequate so that I cannot post it here. Instead I would suggest
to use textps (lprps).

What exactly doesn't work. You can use an if (input filter) like:
#!/bin/sh
#
#  psif - Print PostScript or plain text on a PostScript printer
#  Script version; NOT the version that comes with lprps
#  Installed in /usr/local/libexec/psif
#
read first_line
first_two_chars=`expr "$first_line" : '\(..\)'`

if [ "$first_two_chars" = "%!" ]; then
   #
   #  PostScript job, print it.
   #
   ( echo $first_line ;  cat ) 
else
   #
   #  Plain text, convert it, then print it.
   #
   ( echo $first_line; cat ) | /usr/local/bin/textps 
fi
exit 0
