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.
