Create scenes for each wall elevation, use align view, parallel projection, section planes etc, or any other setup you want, then print the scenes.

you can use "WAYBE" plugin,you can download a demo version from :http://www.waybe.ca/

I'm sorry to say but upfront Sketchup can't do that, maybe with help form available plugins yes. Ask some Ruby Guru's or search the web, they might cost a few bucks but that better than paying for a BIM program that costs hundreds of dollars. If you don't want to go through all of that work then go ahead and use the BIM software. I'm just saying all the knowledge I have right now, I know a lot about SU but I'm barely working with it for a year now. But the point is SU is great for beginners because its easy (five year olds really can use it) and is a great intro to 3-D modeling.
