A job can be cancelled from the app for a full refund at any point before the printer picks it up. Once printing has started it cannot be cancelled, because paper and toner are already being used.
A print that fails is refunded to your Points balance automatically, and a job that stops part-way is charged only for the pages that printed.
Want the money back where it came from rather than as Points? Ask within 7 days and we will send it to the original payment method. The full policy is on the Refund Policy page.
