network_pos_printer

A dart/flutter package to send texts silently (with simple styles like underline, bold, justification, etc.) to a network ESC/POS printer.

It lets you send the data to the printer without previewing a document (usually thermal printers), with the ESC/POS script.

Here an example on how to send texts and cut the ticket:

    NetworkPOSPrinter.connect('192.168.81.80', 9100).then((printer) {

      printer.setBold(true);
      printer.writeLine('Test bold');

      printer.resetToDefault();

      printer.setInverse(true);
      printer.writeLine('Test inverse');

      printer.resetToDefault();

      printer.setUnderline(NetworkPOSPrinterUnderline.single);
      printer.writeLine('Test underline');

      printer.resetToDefault();

      printer.setJustification(NetworkPOSPrinterJustification.center);
      printer.writeLine('Test justification');

      // space blanks before cut
      for (int i = 0; i <= 5; i++) {
        printer.writeLine();
      }

      printer.cut();

      printer.close().then((v) {
        printer.destroy();
      });
    }).catchError((error) {
      print('error : $error');
    });

Some printers will not accept NetworkPOSPrinterUnderline.double, only a single weight will be printed.
