I have a bunch of stuff on my To Be Printed list, too.
I agree hard copy is best, and have an area in my basement bookshelf already set aside for stuff.
The bummer is all the How To's on YouTube that cannot be printed out in a meaningful way. To get around this, I started with printed material, by finding a goos PDF reference, web posting, etc, print it single sided, then as I learn Tips N Tricks pertaining to that subject from a YouTube video, I add my notes in pen on the blank side across from it.
Printing IS expensive. I try to limit myself to 20 pages a day at work to stay under the radar. =)
