OneNote Slides

So I have this teacher that upload pdf slides online for my class. But when I use the printer OneNote Windows so it can be printout in Onenote all the slide go into one page like let's say an example there are 40 slides in a document so everything is under one page and when you want to print the notes out like it prints all the 40 slides and not the one I want specifically. Also, I don't like that once my notes are converted to pdf my gridlines disappear.
