If you are using a supported RetailTime printer and your receipt printer stops printing, please follow the below steps for troubleshooting.
1. Hold the Feed button on the printer. If nothing prints, that means their either is a paper jam or no paper in the printer. In this case, pop open the printer and fix the paper jam or insert receipt paper.
