network_pos_printer

A wrapper to send texts (with simple styles like underline, bold, justification, etc.) to a network POS Printer.

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

    NetworkPrinter.connect('192.168.81.81', 9100).then((printer) {
      for (int i = 1; i <= 10; i++) {
        printer.setBold(i % 2 == 0);
        printer.setInverse(i % 2 == 0);
        printer.setUnderline(i % 2 == 0 ? NetworkPrintUnderline.none : NetworkPrintUnderline.singleweight);
        printer.setJustification(i % 2 == 0 ? NetworkPrintJustification.left : NetworkPrintJustification.center);
        printer.writeLine('test $i');
      }

      // 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}');
    });
