Note on Printing

In a Windows system, pressing the PrintScreen key will capture an image of the desktop. You can paste this into an application such as Wordpad or Paint, and then print it.

In many Unix systems (e.g. in the Math department computer lab) you can do the following:

1. Use the applet to produce your graph. Resize the browser window (by dragging the bottom corners) so that it shows the picture you want but not too much more.
2. Open an xterm window; resize and move it so that it doesn't overlap the browser window, at least not the part that you're interested in printing.
3. Enter the following command in the xterm window.
   xwd|xpr|lpr
4. The mouse cursor turns into a +. Move this into the browser window and click. You should hear a beep or two, and then the printer will print a page showing the browser window.
