Roheen Posted March 24, 2018 Share Posted March 24, 2018 Hi, I have 2 POS machines, both android, to which I've connected some no name Chinese bill printing machines via OTG. They work just fine normally. However, once I've disconnected the printer and started to charge the POSs and then reconnect it then there is issues with printing. Sometimes, it works like nothing has changed but on most times it gives an error. It's happening on both POS machines. Link to comment Share on other sites More sharing options...
