Package totalcross.io.device.printer

Class BluetoothPrinter

java.lang.Object

totalcross.io.device.printer.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();
 ...

Constructor Detail

BluetoothPrinter

public BluetoothPrinter()
                 throws IOException

Creates a new BluetoothPrinter instance, using PortConnector.BLUETOOTH port at 57600 baud rate.

Throws:

IOException

BluetoothPrinter

public BluetoothPrinter(Stream con)
                 throws IOException

Creates a new BluetoothPrinter instance, using the given PortConnector as bridge to the printer. Note that PortConnector can use any port (including infrared), however, it is not guaranteed that it will work with that port. For example, IR does not work on Palm OS devices.

Throws:

IOException

                  int len)
           throws IOException

Sends the given raw data to the printer.

Throws:

IOException

escape

public void escape(int command)
            throws IOException

Sends an escape command to the printer.

                   int value1)
            throws IOException

Sends an escape command to the printer.

Throws:

IOException

escape

public void escape(int command,
                   int value1,
                   int value2)
            throws IOException

Sends an escape command to the printer.

Throws:

IOException

gs

public void gs(int command,
               int value1)
        throws IOException

Sends a GS command to the printer.

Throws:

IOException

gs

public void gs(int command,
               int value1,
               int value2)
