Note: I am able to print java output from Internet Explorer 5.5; this is not possible with some older browsers. If you want to save your results to a file and print them later, you can capture the screen in win 95/98 by holding the win95 key and hitting the print screen key. This copies the screen and then you can paste the image into a Microsoft Word97 document. I don't think this requires the hardcopy program. (Thanks to Robert Kulseth.)
Troubleshooting: Before printing, check to see that everything from the title to the date (in the lower left-hand corner) fits on your screen. If not, then you can close your browser's toolbars and select smaller fonts (8-point works on a 15-inch monitor under netscape with all three toolbars closed). If it still doesn't fit, you may have to use a bigger screen.
If the applets won't run, try restarting your browser. Reloading the a web page didn't reload its applets the last time I tried.
