Can someone help me on one thing

[FullMetal Reg]

How come when i print my pepakura images, the only thing i see are numbers. i ve checked everything from the dotted lines to the colored flaps and nothing seems to work. Am i doing something wrong?

Line thickness, maybe?

idk, but i did everything the tut told me, and i didnt really see anything about line thickness. so maybe something else is wrong, well appreciate the help though.
