Good afternoon,
I am developing an APP on ionic 3, I want to print on a Zebra printer via Bluetooth.
I’m doing this:
this.bluetoothSerial.connect(address).subscribe( () => {
this.bluetoothSerial.write(str).then( () => {
console.log('Ok: );
}, (error) => {
console.log('Error printing: ’ + JSON.stringify(error));
}).catch((error) => {
console.log('Catch printing: ’ + JSON.stringify(error));
});
}, (error) => {
console.log('Error conecting: ’ + JSON.stringify(error));
});
The console shows Ok but nothing is printed…
