    Default Java Loses focus when printing

    I am working on a Java program to monitor meal consumption by members of an organization. They swipe their ID cards, enter PIN, and number of meals they want. System knows if dining room is open and what meal based on time. The system then prints out a receipt on an Epson TM-T88IV receipt printer.

    The system is running in console mode. My problem is that when the system prints, a Notepad window pops up for milliseconds and then the Java program loses focus. The screen reverts back to Windows home screen. I'm using Windows XP, SP3 and the latest Java build.

    Any suggestions on how to prevent the loss of focus would be greatly appreciated.

    Thanks!

    As far as I understand you are running from command line. If the command line loses focus there is nothing you can do because this has nothing to do with java.
    Java can not control the focus of native windows, only of Java Swing frames (or AWT perhaps).

    Cornix,

    Many thanks. I suspected this was the case but wanted to make sure I was not missing something in Windows settings that could prevent the focus loss.
