Printing Costs at Uni

I was wondering if anyone could share their opinions and experiences of uni printing costs and requirements. I'd like to know whether you'd consider it worthwhile buying my own cheap printer to save having to buy printer credit at whichever uni I end up at (Birmingham is my firm, Southampton my insurance but I'm so conflicted as to how my exams went I could be going anywhere).

How much printing do you need to do, roughly?
Do you think printing costs are too much or stack up to a lot over the year?

I'm particularly interested in hearing from other physics/science students as I'm assuming (hoping!) that there'll be less long written assignments for us than the English lot.

Thanks!

Apart from a portfolio, everything else was electronically submitted so can't have spent more than a tenner a year on printing, if that. (at 5p a sheet it was).

Thanks! I forgot/didn't consider that things are electronically submitted. I'm still used to teachers being all "If it's not printed and on my desk I don't care if you've done it or not. Broken printers and lost files are no excuse."
