Ubuntu 12.10 - HP Deskjet 3512 - Can't print

I recently upgraded to Ubuntu 12.10 and all was well using my HP j5700 printer. I bought a new printer HP Deskjet 3512 and was surprised to find it was not supported by this version of Ubuntu. I followed instructions at http://hplipopensource.com/ and downloaded hplip-3.12.10a. I installed the HP drivers and tray successfully (I choose Ubuntu 12.04 as my OS on the website but the installer recognized it as 12.10). Now I have no problems recognizing the printer is plugged in and is idle but when I print the document appears in the queue, the notification from the HP tray says its being printed, and after a few seconds it dissapears from the queue and the message succesfully printed pops up while the document does not print. I have tried .pdf, open office and terminal commands to print all with the same result. However, if the printer is in power save mode, the display panel does light up on the printer. I ran hp-check -t and got:

rob@rob-new-laptop:~$ hp-check -t

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).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

I know this may have resulted from my new and potentially unsupported Ubuntu distro, but I hoped there might be some fix other than returning to 12.04 (Which I installed on another computer and the printer works.) I welcome any help or suggestion. Thanks!
