I was thinking that it might be a good idea to have a forum where we can post how to do things with knoppix that might not be immediately apparent.

For example, if you ever need to print to an HP jetdirect printer but don't want to bother setting up the printing manager and CUPS etc, you can just print to a .ps file, (let's call it print.ps), and then assuming the IP address of the printer was 10.0.1.5 you would type this in a term window:

netcat 10.0.1.5 9100 < print.ps

Voila!
