Click the "Tools" pane then the "Protection" panel in Pdf To Excel Conversion . Choose "Encrypt," then click the option to "Encrypt With Password." From the Permissions pane, you can check boxes that will disable copying, editing and printing.
For example, in the below I've cropped out the images to make printing easier. If I was to convert the .pdf files into printable formats, their edges would bleed into the edges of the pages. I tried converting the .pdf files to .jpg, but with the images so thin, the color was still a little too light for the page. So I thought about converting the .pdf to the same PDF format where the edges of the paper will be visible and the colors will be right, but I'm not confident that it's a straight line conversion.
