What program are you using to open the files? Most programs have a print function if you go to the area at the top of the window called "file"
I made the inserts the exact dimensions of a CD case. So if you print them at 100% size it should be the correct size.
As for the round CD labels. I tried to but I was not able to figure out how to make them the exact dimensions, they may need to be reduced to fit properly. I would try printing one out in black and white at a low grade, to conserve your ink, and by trial and error figure out the size, if you do try that, and come up with a percentage rate, or if anyone else already has... Please share. All the labels are the same exact size, so once you figure one out, you will be able to do them all. I personally have not tried to print anything yet because my printer is not behaving lately.
