They are not too bad - at least the cheaper ones.  We have a 'plotter' 
that prints 2'x3' pretty easily.  The paper is on a roll that is 3' wide 
and like 50' long.

If you need to get it printed look at local copy centers - they might be 
able to help.  Some engineering shops (that sell stuff) might be able to 
help you out as well.

But then again, maybe you are expected to look at your tiny screen and 
figure everything that you need in your head.  After all, pencils cost 
money as well..
