For the past several days, every PDF I try to print shows the print size in multiples of 46.2MB, and half the time, I get a printer error. I recently reloaded Acrobat Reader DC because it wouldn't update (kept telling me I had the latest version when I didn't). The PDFs I'm trying to print are very small (low KBs). What could be the problem?
