Accepting or rejecting print jobs
select Control from the Settings menu,
then select Accept new remote jobs
or Accept new local jobs.
Normally, when you add a printer with the Printer Manager, the printer is set up to accept local print jobs automatically. When a printer is accepting print jobs, lp adds new jobs to the printer's queue.
When you specify that a printer reject print jobs, all new print requests are denied (not added to the queue) until you set the printer to accept them again. If a user tries to print a file on a printer that is not accepting requests, the print job is not accepted and lp displays this message:
UX:lp: ERROR: Requests for destination "printer_name" aren't being accepted.
