This program manages devices controlled by the HP OfficeJet Linux
driver (hpoj).  It attempts to probe your computer for local parallel-
and USB-connected devices, and allows you to specify network addresses
for remote JetDirect-connected devices.
 
If you experience any difficulties in detecting your device(s), then
refer to the hpoj documentation for troubleshooting information.

I only get hpoj to detect my printer after editing /etc/sysconfig/i18n and
change LANG from en_US.UTF-8 to en_US
