printer setup for hp laserjet 6L

[Mrpeabody]

I just got a hp laserjet 6L and I'm trying to set it up I got it to
print by doing a cat > /dev/lp0 ,but the printing is sloppy, how do I
further configure my printer?  I got gostscript from debian is there
anything else I can get to make setup easier.
