Hi
i want to use lpt port for interfacing the switch (for example ,signal the 5v to some pin) listening to some pin and notify my app ?
i use rxtx-2.1-7-bins-r2 in windows.
i used the isPrinterBusy() and isPrinterError() methods and signal the 5v to corresponding pins, but i get true at all ! :|
regards
