Page breaks change positions depending on the screen i'm working on - how do I fix/lock it

Hi all
Hope someone have a tip for me on how to solve my problem.
I have a report in Excel, and everything looks fine when i have my computer docked at work. Then all the pages fit perfectly when i print to pdf (i convert to pdf from the save as pdf/print to pdf in Excel).
My problem appears, when I eg. work from home. If I work directly on my laptop or put it on an external screen throug HDMI cabel, then my 31 page report suddenly becomes 71 pages because of the page breaks have changed.
I can drag the blue lines to make the print area adjusted to the actual 31 paes as intended ,but then it will be a problem next time i'm at the office and dock my computer.
if i in the print section chose to make all columns fit to one page, then i still have a problem with the page breaks so I end with more pages than intended.

Is there any way to make sure the page layout works no matter how I look at it?

Fingers crossed, and thanks for the help!
