Why would an Excel file stored in a shared folder on a Windows 2008 R2 server present itself differently to Domain clients when accessing it?

I have an issue with Microsoft Excel in which when a file is opened, it has suddenly presented a page break that has to be physically moved each time the client prints to get the full page.  If the client has Excel 2016 and clicks "Enable Editing" the page break disappears and the entire document prints correctly.  Clients want no page break to show up by default.  Just a complete image.  This problem is in a small company in which a new Kyocera printer was installed a couple of months ago.  Employees are questioning as to whether this has anything to do with this or not.  Clients are accessing this file from a folder share on a Windows 2008 R2 server of which if they copy the file over for printing it doesn't present the page break.  It occurs just when they are opening the file directly from the server share.  One Windows 7 client is observing these files as all of a sudden very miniaturized.  They have not had to edit the files in the past when opening them for view and printing from the server.

Is there a setting that has been changed in a default area to cause this?  Within the file that is attached, you can see the image of the file with the vertical line page break (top) and the image of the file without the page break (bottom) that the client wants.  Also what would cause this same Excel file to appear miniaturized in the Windows 7 client machine?
