You haven't made it exactly clear what you're trying to do. The print screen function takes a screenshot of your current desktop which then can be loaded in to anyhig that supports copy/pasting images.
I have an ACER Aspire One Notebook PC with a wireless keyboard(Logitech K260). I have Windows 7 64-bit Home Edtion OS. I was using Calibre.com program, listing various books I want to transfer to my E-book. When the home Calibre screen pops up, I press the PrintScreen key on the keyboard and nothing happens. I don't get it printed and I have no idea if that screen is moved somewhere. Certainly not to Notepad(it's empty).
I need to print that screen, but how?
I'll try to use the YouTube How-to, but I'm not hopeful...
