I need help!

My son is going to do Jedi Training on his birthday, so I made a Mickey/Darth Vader design for him. I printed on regular paper to make sure everything looks right, but when I print, the Mickey has a very noticeable thin white "border" around him. It is only slightly noticeable in Word, even when the view is at 100%, so why is the white area around him much larger when I print? Is there any way I can fix it? I tried the "set transparent color" thing, but it did nothing. Am I just stuck with it like that?

I wanted to post the picture, but I have no idea how since I created it in Word. Thank you to anyone who gets what I'm saying and responds, lol!
