Installing USB printer.

Okay I'm trying to use a Epson StylusC40X on my RedHat 7.3 box.

so from the command line I type printconf-gui. and it give me the nice
little gui the device listed there is /dev/lp0 do I want to change this
to some USB dev since I'm using a USB connection? or should it still be
lp0 since its a local printer? If it should be a USB dev how would I
find out which dev to use?

Thanks,
Carl Parrish
