Hello K. Hilger,
The Windows Photo Gallery does not read or Open PDF files.
The best way to print PDF files is like you said, take a screen shot by using print screen.
Save the file as .jpeg and then open with the Windows Photo Gallery and you should be able to print it.
You might not need to make any changes with your printer.
