Thank you for your response. I've got a workaround that does what I want to do. I exported the pages of the pdf as images (using PDF Expert software), then added a .html file to the folder of images that displays them on a web-browser. When I then print that webpage the printed pages are filled with content, using whatever number of pages from the original pdf that fit on the printed page.
I've attached the .html code below, for those who want to do a similar thing and stumble across this thread online.
