When I first read the description of PrintDeskTop I thought this was quite a useless app: I already have a key (PrtScr) to print my screen.
But then I realized that PrintDeskTop is intended to print the screen right onto paper, in your own home printer, rather than copying the contents to the clipboard.
Though you usually print images, documents and other files from their respective applications, PrintDeskTop makes it even easier as it enables you to print with just a simple click or a keyboard shortcut.
Being so simple, the program falls short of expectations when it comes to configuration settings. There's no way to customize printed images, and even the keyboard shortcut configuration is based on the Windows native shortcut system, but not on one offered by the program.
