@spipitone Being able to print the quizzes/tests has always been around, there are even browser extensions that you can install that make it print very clean. I think your best bet if you want to block this is to look into one of the lockdown browsers that can be purchased such as Respondus, Proctorio, HonorLock, etc. Yes, I realize this is an additional cost but might be the best answer. While someone could probably write a script to block printing, students could still copy and paste/screenshot and still blocking anything does not prevent students from using their cell phones to take picture of the exam.
We use Proctorio as it also has the ability to record the student during the exam (this is for the cell phone piece.). I know this technology is very controversial but because some of our courses ultimately are high-stakes exams, we have to have some sort of test security in place. We have also tried to teach faculty to use test banks when they have to use multiple choice and to create other means of assessment that even if shared would not be super helpful.
I know this is not the answer you are looking for but thought I would share.
