Ubuntu 12.04 won't find printer (HP Laserjet p2015dn) after reading several forums

Ubuntu 12.04 ( Kernel: 3.2.0-38-generic) won't find printer. I've read several forum posts and tried all I could. Printer will stop being found on a regular basis since an update of a few months ago. Started having to reinstall hplip, etc. before it would work again. This time, printer just refused to be found.

I tried reinstalling hplip driver (That is what usually would fix it)
 http://hplipopensource.com/hplip-web/gethplip.html

I tried CUPS method
 http://localhost/631

After many tries of hp-setup both from command line and GUI I ran

$sudo system-config-printer

and deleted the queue, but there were no usb printers to add, only parallel (LPT#1) and URI network. My HP p2015

Then started over

I tried
ikmguy@ikmguy-desktop:~$ kdesudo sh hplip-3.12.4-plugin.run
sh: 0: Can't open hplip-3.12.4-plugin.run
ikmguy@ikmguy-desktop:~$ ls -al hp*

ikmguy@ikmguy-desktop:~$ hp-setup

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]
PYEXT SCANCONF QUEUES PERMISSION

Status Types:
    OK
    MISSING - Missing Dependency or Permission or Plug-in
    INCOMPAT - Incompatible dependency-version or Plugin-version
