Hi! I need to make a scanner server - a program in a
server that will listen to other PCs request for using
the scanner, like a printing server. The client needsTake a look at JTwain:
JTwain supports all kinds of digital cameras and scanners.
You can use Java to access, contorl digital cameras and scanners, and of course,
to acquire images with flexible settings.
The developers' guide is available @ http://asprise.com/product/jtwain/devGuide.php
Here is the sample code:
try {
   // the SourceManager manages and controls all the data(image) sources, eg. scanners, digital cameras,
   Source source = SourceManager.instance().getDefaultSource();
   source.open();
   // Enables or disables the UI
   source.setUIEnabled(false);
   Image image = source.acuqireImage();
   ... // Uses image here ...
   // Saves the image into a file
   source.saveLastAcquiredImageIntoFile("test.jpg");
}catch(Exception e) {
   e.printStackTrace();
}finally{
   SourceManager.closeSourceManager();
}Good luck!
