Review on Barcode Label Printer by Andrew Frison

I use this portable printer to print personalized QR code stickers on the fly. Works very well and reliably. Print quality and print speed are excellent. The included phone app works pretty well, although it would be nice to have more developer options. I basically reverse engineered the USB interface and can now automatically print from Python (only tried on Linux). This works great and meets my requirements exactly. I can wholeheartedly recommend this printer.
