label_printer 0.0.4

Print label using image, boundary, ... with flutter

label_printer

The library allows to print label using an ESC/POS thermal WiFi/Ethernet printer.

It can be used in Flutter or pure Dart projects. For Flutter projects, both Android and iOS are supported.

To scan for printers in your network, consider using ping_discover_network package. Note that most of the ESC/POS printers by default listen on port 9100.

Simple print Label:

final printer = LabelPrinter('192.168.0.1', 9100, {
    printerType: PrinterType.label,
    printMode: PrintMode.overwrite,
    metric: Metric.mm,
    direction: Direction.up,
    dpi: 203,
    verticalGap: 2,
    horizontalGap: 2,
    labelWidth: 65,
    labelHeight: 35,
});

printer.image(image, {
    numOfSet: 1
    numOfPrint: 1
    xOffset: 0
    yOffset: 0
    alpha: 50
})

Simple raw commands:

// PRINT 1,1
// EOP
printer.raw([80, 82, 73, 78, 84, 32, 49, 44, 49, 13, 10, 69, 79, 80, 13, 10])

// Or if you want to using LATIN instead
printer.rawText('PRINT 1,1\r\nEOP\r\n');
