I don't think I can use the > ":if=<filters files>" in the /etc/printcap.? add the line :if=/usr/local/bin/lpf: to your /etc/printcap entry. and /usr/local/bin/lpf being a shell script like (in the simplest case): #!/bin/sh exec sed 's/$/^M/' note that ^M is a literal control-M (carriage return) produced in vi by typing ^V (control-v) in front of it. During debugging you can consult /var/log/lpd-errs.
