Using Google Drive with exported PDF/Musescore parts

I really don't know in which bucket this question should be tossed, so I am going post it here.
I use have been placing my exported musescore parts on Google Drive.
These are musescore parts that have been exported as PDF files. The parts look fine when one opens them on the Google Drive, but there are some parts that print out off center. In other words, only a portion of the music actually fits on the printed page. I am trying to find out what is causing that effect, and was wondering if anyone else had a similar problem/solution. I tend to think it is not a musescore problem, but some kind of "interface" (I am computer illiterate) between the PDF file and Google Drive.
I apologize in advance for posting here.
I just finally thought I had found a way to easily and conveniently get parts and scores out to my jazz septet here in Springfield, MO so they could shed their parts before the gig, (novel idea!) and it was partially successful... Just need to work out this problem.
