This tiny program installs quickly on your PC, ready to spring into service when you summon it from your Start Menu. Activate PrintDeskTop, and it shows you a screen saying it's printing. Then it shows you a screen saying it has printed, and lo and behold, there's your desktop's twin on your printer. That's it.
If you want to make this even easier, you can set a key combo for PrintDeskTop. The vendor's instructions say: "Click Start->All Programs->PrintDeskTop, Now, right-click the PrintDeskTop icon and then click Properties. In the Properties dialog's Shortcut tab, click inside the "Shortcut key:" box and then click Ctl+Alt+p (if you want the recommended shortcut key). Finally, click OK." I tried it, and it worked like a charm.
