did you try to run the tool printconf (apt-get install printconf)? it 
automagically configured my pc using cups. I tried configuring using 
http://localhost:631/ for a HP 5150 but it didn't go, printconf made it 
very easy.

Description: Automatically configures USB and parallel printers with CUPS
  Foomatic is a printing system designed to make it easier to set up
  common printers for use with Debian (and other operating systems).
  It provides the "glue" between a print spooler (like CUPS) and
  your actual printer, by telling your computer how to process files
  sent to the printer.
