It is possible to print a copy of almost anything you want to from an eBook on a computer, but it takes a little work.
Obviously, the publisher doesn’t want you to be able to just hit a “Print” key and print the whole book out. That would violate copyright rules. So, if I want to just copy a particular page or so, the way that I do it is to get whatever I want to print on the screen of the computer. I make sure that it is centered and sometimes I even have to do two print jobs to get it all in, but with a little imagination, I can usually get it where I want it. Next, I hit the “Print Screen” key on the computer (yes, they all have one hiding somewhere, usually in the upper right hand area). After doing that, I open up “Paint” (it is called 3D Paint on the version of Windows that is on my computer). Some version of “Paint” comes with most “Windows” packages. It is a neat program that can be used to turn an image on the screen into a graphic that can be printed. Once “Paint” is open, I just “paste” the image that was put on the “clipboard” of the computer during the “Print Screen” operation and there it is. I can then print the image from the “Paint” menu item. You obviously wouldn’t want to print MANY pages at a time that way, because you would have to repeat the process of “pasting to Paint” with each page, but it is a technique that I use quite often to make a copy of something in an eBook.
