Updated hplip packages that fix several bugs and add various enhancements 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.
The hplip packages have been upgraded to upstream version 3.14.6, which provides a number of bug fixes and enhancements over the previous version, including hardware enablement and new functionality, such as the Service Location Protocol (SLP) discovery feature. (BZ#1077121)
- Previously, HPLIP did not correctly handle CUPS denying a requested operation, such enabling or disabling a printer. As a consequence, operating HP Device Manager as a non-root user did not prompt for the root password when the root password was required for an operation. With this update, the password callback is correctly implemented, and operating HP Device Manager as non-root user now always prompts for the root password when required.
- Prior to this update, the use of an uninitialized value could produce incorrect output from the hpcups driver. The underlying source code has been modified to initialize the value before it is used, and the described unexpected behavior is therefore prevented.
Users of hplip are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
