Hi,
It often comes as a surprise, but the print view and even the print preview are approximations of what will be printed. Print preview is much closer, though.
Word decides what goes where in a document based on the printer driver being used. This is software distributed by the printer manufacturer. The settings for each printer are different.
Word documents will often print differently on different computers.
You can minimize this by using wide margins and dynamic page breaks like page-break-before formatting for certain headings.
Screenshots and sample documents can help us provide more precise help.
Here's how to post a screenshot:

If you want, save a sample document with the problem on OneDrive or Dropbox and paste a link here. Remove any confidential or sensitive information first. I can take a look at it. I may be able to fix it for you and explain what I did.
I hope this information helps. Please let me know if you have any more questions or require further help.
Regards
