Problems with word 10

[Campfire_Dog]

I have just joined this forum and have a question. I have the office and student 10 program. I have had huge problems with this program and am not sure that I just have limited skills. I type a lovely letter or resume and then when I go to print it, only a small part of the body shows up and that is all that will print. Very frustrating. I want to be better. I need help.
Thanks in advance

Hello, me again. I realize that the lines that do not show up have a broken line under them so what is the answer to the mysterious broken line and how do I get rid of it????
