So of course the night I need to print a really important assignment, my MBP can't find my HP Photosmart 5520 printer over USB. I downloaded the new drivers for El Capitan from HP, but my MBP can't find the printer in System Preferences or through the HP setup program to re-add it. I can find it via wifi, but the wifi connection removes the text from my document and only leaves the pictures! I really don't have time to revert to Yosemite just so I can print this project and turn it in tomorrow! Looks like I'll be borrowing my fiance's PC, but this is incredibly frustrating! Anybody else have the same problem and find a fix?
