The most reliable way to prevent new print jobs is to pause the printer queue or set the printer to offline status. Once repairs are done, the administrator can resume or set the printer back online.
The most reliable way to prevent print jobs from being added to the queue while a network printer is being repaired is to pause the printer queue on the server that is managing the print jobs. This action will stop new jobs from being processed without disrupting any jobs that are currently in the queue.
As an alternative, the network administrator could also change the printer's status to offline, either through the printer's management interface or from the devices and printers panel in the operating system. Once the repairs are complete, the administrator can simply resume or change the printer status back to online to allow printing to continue.
Therefore, pausing the printer queue or setting the printer to offline status are the most reliable methods for ensuring that no new print jobs are processed during maintenance or repairs.
