It will give that message of not being able to connect to the X server, if your desktop is not run from root, but your terminal is in root. It can also happen from running inside a jail.
 
If you want to run hp-setup as root, you can prefix it with the DISPLAY variable with value, like so:
# DISPLAY=:0.0 hp-setup
First you will have to find out what the correct value is, by doing echo $DISPLAY as your normal user.
 
This is my results like root:
Code: 
 # echo $DISPLAY
:0
and then
Code: 
 # DISPLAY=:0.0 hp-setup
DISPLAY=:0.0: Command not found.
like normal user:
Code: 
$  DISPLAY=:0.0 hp-setup

Done.

Ideas?
 
The root user's shell is csh(1). (No, do not change it.) So either set that environment variable with that shell's method ( setenv DISPLAY :0.0) or start sh(1) or bash(1) to do it as shown above.
