If your printer is only printing blank paper, please make sure that the paper is inserted correctly. The printer should always pull the paper roll from below, not above. 

If your tickets are printing at random times, please check that you have set everything to the correct time zone. In the UK, for example, the time one should always be London - Greenwich Mean Time in Winter time and British Summer Time in Summer time.

If your printer is only printing logos, please contact Deliveroo Support.
