I make my own. It only takes a second. You can have whatever size and colours you want, and whatever quality paper too.
That's very sweeping! For a start, my experience is that nothing involving a computer ever "only takes a second".
I expect a lot of us have some sort of A4 black and white printer, and if you only want to work in pencil neither the print quality nor the paper quality will be particularly important, but Andrew was talking about good quality large ms paper so he would need an A3 printer with all its associated running costs and a source of good quality paper (not often available in quantities less than a ream - 500 sheets).
