It is impossible, in all languages.
You will need some program on that computer to make it work.

If you could run a program on that machine, it could be done.

Let me call the computer with a fixed IP, S so I don't have to keep describing it with each reference to it.

What I am proposing would be a client and server that communicate to capture, send and recieve the screen shot.

Using java.awt.Robot, you can use
BufferedImage createScreenCapture(Rectangle screenRect)
to get a screen capture.

The easiest way to transmit the image would probably be if the screen capture program also used a ServerSocket and sent the image through the socket back to the remote computer.

As most servers, the screen capture server would run constantly on S and be waiting for requests for the screen capture. The client simply connects when it wants a screen capture. When a connection is made, the server makes the image and sends it through the Socket back to the client.

This kind of software is aleady available.. Virtual Network Computing(RealVNC) uses the same kind of client/server architecture.
