In RedHat's control-panel utility, you can clock on the printer icon
and generate entries for your printer. It updates the /etc/printcap and
creates appropriate filters if necessary.

Run

        control-panel

as root.

Your filter needs to include a short shell script that will send an esc
commend to the printer telling it to include the carriage return with the line
feed. Since you don't say what kind of printer you are using we can't say what
the esc-command should be.

For my HPLJ 5MP I use a short script "hpfilter":

        #!/bin/sh
        echo -e -n "\033E\033&k2G'
        cat
        echo -e -n "\033"

I have it located it saved as "/usr/bin/hpfilter" and it has to be set as
executable for the group using the printer. I used "chmod 755
/usr/bin/hpfilter" but you may want to use a different setting. The script has
to be called by printcap. The pertinent lines in mine read:

        :sh:\
        :if=/usr/bin/hpfilter:\

This will get rid of the stair stepping. Barkakati gives a similar script in
Linux Secrets, but I could not get his version to work.
