Which command is used to check the status of the print queue?

The command used to check the status of the print queue is 'lpq'. This command displays the current jobs in the print queue, allowing users to see which print jobs are pending, the status of those jobs, and any relevant details such as the job ID and the user who submitted the job. This functionality is essential for monitoring printing tasks, especially in environments where multiple users share printing resources.

In contrast, while 'lpr' is a command related to sending files to the printer, it does not provide information about the status of the print queue itself. The command 'dmesg' is used to display the kernel's message buffer and is primarily for diagnosing hardware and system issues, not for printing tasks. Lastly, 'lsdev' is not a standard Linux command for checking print queues and is more related to listing device configurations. Therefore, 'lpq' is specifically designed for querying the print queue status.
