@Madcamper:
Which version of CUPS are you running? Use the command: cups-config --version
I am pretty sure that cups1311.tczl will work for you once you get the cups daemon started, as described in the info file. Either:
1. Run: sudo /etc/init.d/cups start or
2. Add the line to your /opt/bootlocal.sh file
If you currently have CUPS 1.4x in play, you will need to uninstall it before going back to CUPS 1.3.11. Otherwise, the two versions will fight each other.
Where did you get the driver for your NX100?
