Re: [newbie] HP Jetdirect printing
Greg, Take some canned air and blow the crap out-a the fan. Then put a few drops of 3-in-1 oil on the fan shaft and no more noise.

Re: [newbie] HP Jetdirect printing
Try using the IP address of the printer for the host name, and a queue name of "raw" (no quotes). I have an HP LJ4M Plus with internal JetDirect card and it works fine for me. Note that the version of printtool supplied with 7.0 and 7.1 doesn't seem to work. Others have experienced this. If you can get hold of the printtool RPM from Red Hat 6.1 or 6.2 and install it, you should be fine.
