Design and print Nelko P21 labels on your computer
Fyne-P21-Print gives the Nelko P21 a desktop label designer. Arrange text, pictures, barcodes and shapes, save a design, and print it through the printer’s Bluetooth serial connection.
Pair the P21 in your computer’s Bluetooth settings first. Windows uses its assigned COM port; Linux uses BlueZ and may request permission to open an RFCOMM connection. The project provides desktop releases, with a source-build route for configurations without a matching package.
