I use this printer with my square app. It easily connects via Bluetooth. You can print order tickets, receipt & order ticket stub for customer. I operate a food truck and I plugged in a cash drawer to the printer. It works amazing.! Love itUnfortunately I couldn’t get my first one to connect to my ipad so sent it back for a fully wireless one. Company had no problem taking it back and I was refunded all but $54 which was a “restocking fee” which is a little frustrating. Hopefully this next one will work for me!I was so worried I could t set this up with my cash drawer and iPhone with Square app. I didn’t have WiFi, but it worked great using Bluetooth! My phone has cell & data, and I can easily ring a sale, print any tickets or receipts, and the cable to the cash drawer I bought separately on here pops open when triggered through my phone app and the printer. AWESOME! I love that I can print kitchen tickets, as well as customer checks and receipts, all through this mighty little printer.I can't connect to WiFi through following the set up instructions, I was stuck at Wifi connection -> Site Survery -> nothing shows up to connect the WiFi!Very bad set up experience as it doesn't work at allThe printer is great and works as described, but the product description is misleading. It says that it is a bluetooth printer AND cash drawer, which would imply they both are bluetooth. In the extra bullet points it further states its not a usb cash drawer (which would lead one to believe it was bluetooth because nothing else works with Square). What they send is a cash drawer that connects via a phone jack cable. This is not stated anywhere in the description. I needed a bluetooth cash drawer to go with the bluetooth printer and my wireless computer system. It also advertises that it is for a SQUARE POS system. Well, that uses USB or bluetooth. NOT A STUPID PHONE JACK CABLE!! I looked all over for what I thought this was and find it isn't! Very disappointed. Now what do I do with a useless cash drawer? Oversize paperweight?Works well and prints quickly and clearly. The only complaint I have is when obtaining the IP address using the printer, it spits out a multi-foot long piece of trash that is unnecessary with the IP at the very bottom.I used this with an IPad with the Heckler Windfall stand on an APG cash drawer. I was able to hook up the APG cash drawer directly to this printer, and then used the IPad Bluetooth to communicate with the printer. Works like a charm, never an issue with jamming either. I am using the Square POS app. Plus there isn't a delay when printing a receipt with the bluetooth.I ordered this unit with my my android and square, square does not see the printer at allWorks perfectly on ipad without hesitation..!Delivery from the supplier is very fast and efficient. Product itself has some set backs which needs to considered before buying this particular printer. Very expensive compared to other peers, No plug n play installation and instructions are very complicated. Bluetooth sharing for printing between two systems won't work. Driver CD has to be downloaded online.Excelente impresora de recibos, super rapidísima y muy fácil de configurar. Totalmente compatible con iOS y android, lo utilizo con izettle y trabaja a la perfección.La impresora llegó bien y funciona perfecto, imprime muy bien y es muy rápida, muy recomendable.Great as described
