I have sent a drawing of a floor plan to layout and it’s displaying as heavily pixelated so I can’t print it, how do I can change the settings to Vector or Hybrid to get vector linework?
I want to print in A3.
For the vector info, This video, about 5 minutes in. And the whole series has been VERY useful to me when it comes to layout. 
The information about the paper sizes is in the previous video. You usually set that up in the very beginning when you open a new project, but I believe you can also get there using file> document setup.
Please don’t double post.
This was so helpful, it explained everything that I needed to know. Thanks so much
