If you have submitted a job you no longer want printed, there are multiple ways to cancel it so you will not have to pay the print charges.
Print jobs are held for up to 48 to be released, afterward the job will be automatically deleted and no charges will be incurred. If you have other jobs in queue you do wish to release, use Sharp multi-funtion devices and avoid the "print all" button.
(Do not click "Print All")
(Highlight the desired job, click "Print" button on the right)
