Additional assistance with SCO Unix

Problem:

I was not able to disable the option "use extended remote printing protocol" option in the SCO configuration. Now when I print, I receive warning messages in the log stating "unrecognized control line".

Resolution:

You can now modify the /etc/printcap file manually. Open this file in an editor such as 'vi' or 'edit'.

Locate the printer entry for this printer, it should look something like this:

  hp4:\
    :lp=:rm=192.168.1.53:ex:rp=hp4:sd=/usr/spool/lpd/hp4:

Remove 'ex:' from the line. It should now read similar to this:

  hp4:\
    :lp=:rm=192.168.1.53:rp=hp4:sd=/usr/spool/lpd/hp4:

Be sure to leave a colon (:) separator between each entry. Now you can save the file and try printing again. This disables the extended options that are not included in the original rfc 1179 specifications.
