buzzer integrated

[fabry84]

Hi, congratulations, your project also works very well with Italian printers. Can I ask you if you have also planned to activate the buzzer integrated into the printers when cutting the paper? or is it possible to send escpos commands directly to the printer?

Thank you

Hi Dantsu, could you give me some help? I found the code for the internal buzzer, but when I send it I get an error. I attach the code and error, what am I doing wrong?
Thank you
TcpConnection printerConnection = new TcpConnection("192.168.1.151",9100);
printerConnection.write(new byte[]{0x1b,0x42,0x02,0x01});
printerConnection.send(1);

The error is in the line printerConnection.send(1);
