Client sys assigns LPT1 to a net printer

How can I make XP forget what it thinks it knows about this shared printer and allow me to set it up new? When I install the printer, an hp3330, on the client sys it finds the shared printer and sets it up on LPT1, which of course won’t work, without allowing me to change the port config. I’ve tried browsing for the printer and typing in the location and the result is the same. It will set up and print to other net printers fine.
