This is the Cino Printer GO support app. It can communicate with the mobile portable printer via the phone's WiFi. It can edit images, text, doodles, QR codes, barcodes, and date/time stamps, then transfer them to your portable printer and print. It can Save images in the History so as not to always send them but to print them directly whenever you want. You can query the status of the mobile printer such as battery life and check its settings. You can choose to print in one line or multiline to print larger shapes or lettering.
