Package totalcross.io.device.printer

Class BluetoothPrinter

  • Direct Known Subclasses:
    CitizenPrinter, MPTPrinter
    public class BluetoothPrinter
extends java.lang.Object
    Used as interface to printers that uses Bluetooth to communicate with the device. See the CitizenPrinter javadocs if you plan to use one.

    Note: during tests, we found that some printers require to fill their buffer to start printing. So, if you have problems printing, try the following code after you instantiate this class: 

     cp = new CitizenPrinter(); // or new BluetoothPrinter();
 cp.write(new byte[2048]); // fill the buffer
 cp.newLine();
 ...
