DESCRIPTION

hp-check is a command-line utility provided by the HP Linux Imaging and Printing (HPLIP) software suite. Its primary function is to diagnose potential problems with HP printer installations, including missing dependencies, driver issues, and communication errors.

It performs a comprehensive system check, identifying missing or outdated software packages required for proper printer operation. hp-check provides clear explanations of any detected issues and, where possible, offers solutions, such as suggesting installation commands for necessary packages. The tool can operate in interactive and non-interactive modes, allowing it to be used in scripts and automated environments. hp-check can also be used to gather debugging information for reporting issues to HPLIP developers.

It's an essential tool for users of HP printers on Linux systems, streamlining the troubleshooting process and ensuring a smooth printing experience. It helps to resolve configuration, installation and connection problems and facilitates system setup for initial printing.

CAVEATS

The effectiveness of the `--fix` option depends on the specific issues detected. It may not be able to resolve all problems automatically, especially those requiring manual intervention. Requires root or sudo privileges for many operations.

EXIT STATUS

hp-check returns an exit status of 0 if all checks pass successfully. A non-zero exit status indicates that one or more issues were detected.

DEPENDENCY MANAGEMENT

The utility relies on package management tools such as apt, yum, or zypper to install missing dependencies. It attempts to identify the appropriate package manager based on the detected Linux distribution.

HISTORY

hp-check is a core component of the HPLIP software suite, which has been developed and maintained by HP and the open-source community for many years. The command has evolved alongside HPLIP to support new printers, operating systems, and software dependencies. Its initial purpose was to ease installation and diagnosis of HP printers on Linux, a historically challenging task. Continuous improvements and updates are made to enhance its capabilities and address emerging issues related to printing technologies.
