[conspire] HP LaserJet4 - CUPS lists printer twice

[Darlene Wallach]

I picked up the HP LaserJet4 printer from Bruce today. Since it has a
parallel port, I connected it to my desktop VA Linux 420. I am using
CUPS to add it so I can print. The "List Available Printers" lists it
twice:
- add this printer HP LaserJet 4 Plus (HP LaserJet 4 Plus LPT #1)
- add this printer HP LaserJet 4 Plus (HP LaserJet 4 Plus LPT parport0 HPLIP)

Why is it listed twice?
Which one should I add? Does it make a difference?

Thank you,
Darlene Wallach
