If you plan to change the way a printer is used or decide to take a printer out of service, you should set up the LP print service to reject additional print requests. Then, move or cancel any requests that are currently queued to the printer. You can use the lpmove command to move individual or all print requests to another local printer.
Request IDs are not changed when you move print requests, so users can still find their requests. Print requests that have requirements, such as a specific file content type or form, that cannot be met by the newly specified printer cannot be moved. These print requests must be canceled.
