Getting the lexmark z23/33 printer to work in Slack was a real pain, but once I understood init scripts, etc,
it was a breeze - that why I love Slackware- it teaches you so much coz everything has to be done by hand ;-)
Anyway, Here are the steps:
1) Become root.
2) Make the directories /etc/rc.d/rc.4 and /etc/rc.d/rc.5 because Slackware does not use sysV-like init scripts.
3) Install the printer driver after downloading it from Lexmark's site.
4) Add these lines to /etc/rc.M (as root of course)
That's it! reboot or start /usr/sbin/lexlmd as root manually. Then you can verify by starting from the console as
root, "z23-z33lsc" and after about a couple of seconds, it should show you the printer cartridge ink levels.
