[Printing-user-general] Adding a new printer via CUPS web interface

Hi,

I'm trying to add 2 new printers using the CUPS web interface in Redhat v3. I
have installed the 2 ppd files in /usr/share/cups/model:

/usr/share/cups/model/WCM20.ppd
/usr/share/cups/model/HP-DeskJet_6840-hpijs.ppd

In the web interface http://localhost:631, i click on add printer, fill in:
Name: xerox
Location: 192.168.0.13
Description: xerox

click continue.

Now heres where I'm confused. I'm not sure what device to use. Its a shared
network printer so I assume I'm going to use IPP. Can someone help me out w/
the device address.

Thanks.
