That's interesting. I use lj2100 with apsfilter via printcap. aps1|lp|laserjet;r=1200x1200;q=medium;c=gray;p=a4;m=auto:\ :lp=/dev/lpt0:\ :if=/usr/local/etc/apsfilter/basedir/bin/apsfilter:\ thanks anton _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
