unable to install Dell Photo Printer 720

[Phill Atwood <me@phillatwood.name>]

This what I did:

- downloaded the driver.  The Dell 720 is a rebranding of Lexmark and
RedHat has a package for the driver.
- I untarred the tarball
- used alien to create .deb files
- used dpkg -i to install the .deb files
- used "Add a Printer"
- it detected my printer USB port but could not offer me the z600*
driver

I'm using etch and gnome.  Anybody have success installing this printer?
