HP C4640 Not Detected Under Ubuntu 9.04

Trying to get a new HP C4640 to work under ubuntu 9.04. Hplip did not find it with the default hplip that ships currently with Jaunty.

https://h10057.www1.hp.com/ecomcat/hpcatalog/specs/provisioner/99/Q8411A.htm

Implies that Hplip supports this model, so I upgraded successfully to 3.9.4b. Still does not find the printer.

Output from hp-setup below:

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to
determine if the proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already
built HPLIP supplied tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile-
and run-time dependencies).
