I can't print anything from powerpoint 2013. I can print in word or other office products, but not powerpoint. It acts like it will print but does nothing. After changing advanced setting and unchecking 'print in background' the print status box pops up but the 'preparing.....' prompt just stays on and nothing ever happens.

I want to print 3 per page handouts in grayscale for attendees at a seminar. Nothing.

You can refer to the thread below to fix printing issues in PowerPoint:
