The lpstat command is a powerful utility used to display status information about the CUPS printing system. It allows users to check the status of printers, jobs, classes, and the CUPS server itself. lpstat can provide details such as whether a printer is enabled, accepting jobs, and any error messages that might be present. It's an invaluable tool for troubleshooting printing problems and managing the print queue. The command offers various options to filter the output, allowing users to focus on specific aspects of the printing system. It is often utilized in scripts and automation processes to monitor printer health and automatically report issues. With different options, the command can list all printers, specific printers, jobs owned by a user, and even server status. The status can be queried for specific printers and it works great in scripts for automated monitoring.
It's an indispensable tool for system administrators and end-users alike for managing and troubleshooting printing in a CUPS environment.

The output and behavior of lpstat can vary slightly depending on the CUPS version and the specific Linux distribution.

The lpstat command returns 0 on successful completion. A non-zero value indicates an error.

The command relies on the CUPS configuration files, typically located in /etc/cups, for its information.

The lpstat command has been a standard part of Unix-like operating systems for a long time. It originates from the System V printing system and has been adapted and modernized within the CUPS (Common Unix Printing System) environment. Its primary function has remained consistent: providing status information about the printing system.
