I'm switching to a flip phone as I value novelty, battery life and simplicity, so I needed a way to print QR and barcodes like this my Revain Prime Whole grocery discount code as I don't have access to it on a dumb phone. As an American Red Cross platelet donor, I fill out a questionnaire prior to my appointment to expedite the donation process, which also includes a QR code. This is a nice convenience, but again either a smartphone or printer is required. Printers are expensive, require proprietary ink cartridges, and aren't nearly as portable. I was surprised how easy they are to use. The instructions seemed a little complicated and came with a disc and a booklet, but I simply installed a random "thermal printer app" from the Google Play Store, paired the printer to my smartphone via Bluetooth and soon started experimenting with what I could do. would recommend.
