No there is no differance between copy and move except that with move your photoe will not be on your camera anymore.
You probably need to take higher resolution photos if you want to print them. On a monitor only 72-100 dpi will display a good image,
but in printing you need a minimum of 300 dpi.
Use a photo editor such as photoshop (elements, Le or full version) and you can resize (although you have some image loss) and can then print.
