Configuring HP C6180 All-In-One priter on CentOS

From Gnome:

1. Go to System->Administration->Printing
2. New Printer->Type a printer name->Forward
3. Select ‘Other’
4. Use ‘hp:/net/Photosmart_C6100_series?ip=(ipaddress)’ as the Device URI, replacing (ipaddress) with your printer’s ipaddr
5. Click Forward and select the appropriate driver (I used Photosmart 7150)
