Printer Issues

Ever since we switched over to Shopify POS we have had trouble with our printer just randomly stopping throughout the day- We have to shut everything down, restart, reconnect, and then it seems to work again. However, this happens at least once a day, which is not ideal in a busy retail setting. We thought it was because the initial printer we ordered was a bluetooth connection so we returned that one and got one that connects via LAN- however we are still having issues. Anyone out there that can help? We have never had printer issues like this when we were with Quickbooks, and it is becoming extremely irritating for both us and our customers.
