hplip bug fix update

Updated hplip packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 6.

The hplip packages contain the Hewlett-Packard Linux Imaging and Printing
Project (HPLIP) which provides drivers for Hewlett-Packard printers and
multi-function peripherals.

This update fixes the following bugs:

* Previously, certain Python scripts used the interpreter line "#!/usr/bin/env
python". Due to this issue, these scripts used an incorrect version during the
execution. With this update, the interpreter line is changed and uses the path
/usr/bin/python. (BZ#608003)

* Previously, the license text was missing. This update adds the license text to
the hplip-common sub-package. (BZ#613707)

* Previously, the hp-toolbox utility failed to add new printers due to incorrect
handling of CUPS authentication in the cupsext Python extension. This update
corrects the handling. Now, new printers can be added successfully. (BZ#616569)

* Previously, the CUPS Web Interface button, displayed in hp-toolbox when no
connected devices were shown, led to an incorrect URL. This update corrects this
URL so that there is no error message shown. (BZ#633899)

* This update upgrades HPLIP to the current version to allow support for a wider
range of HP printers. (BZ#652255)

All HPLIP users are advised to upgrade to these updated packages, which fix
these bugs.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
