Java: get printer status (paper low/out)

问题

I have printed this way

FileWriter imp = new FileWriter("COM2");
while ((linea = br.readLine()) != null) {
            imp.write(linea);
            imp.write(0x0A);
}

Well now Im using the port COM2, I have a printer that receive a hex code and its response will back in type byte, I dont know how to do it with java. Somebody has done it before?

Thanks.

You could try using javax.print.attribute.standard.PrinterStateReason

This class is a part of the javax.print.* packages.
