printing Word doc changes the formatting

I don't know whether I explained this clearly. I have a document on Word that is in an outline format. There are lines starting at the left margin with the major point I'm making. A subsidiary point is indented. Another point subsidiary to that is further indented. On the monitor it looks perfect. But when I print it the indents are all changed. I tried opening it in Pages and it opened way out in the corner of my screen, with a part of the page cut off. I don't know how to use Pages and to start learning it now when I have to get this document printed isn't feasible. No one else has had a problem with printing a Word document that is in an outline format?

It's a document I typed in order to give a talk. The way I can best speak is using an outline format. But when I print it (or put it in a pdf, or open it in Preview) the indents are rearranged. I no longer have the outline format as I see it on the screen.

This is weird. After trying to print it in pdf, I found the pdf had reformatted, just like the printed version. I then tried printing it in Preview, and it was the same as the pdf. But just before getting this message I tried again in Preview and it opened as I had typed it. I don't understand what could have been different, but as long as this doesn't revert, I'm set to go.

Thanks.
