UC Irvine gives you 30 pages of printing per month if you are an arts student. Or if you know someone who works at one of the artslabs
Otherwise No free printing really (save through specific schools and student programs). To print at the library takes a copy card (which can also be used at copy machines to make copies). Last i checked the rates were reasonable enough. I think 2 bucks for the card and then 5c for print from computer, 7 from copier.
I bought the samsung ML-2010 though a while ago and i haven't needed to print on campus for awhile
hrmm edit : let me think about printing at UCI a little harder for one sec
Dorm Communities - Free print, bring your own sheets (at least it was 3 years ago)
Artslab - 30 pages/mnth
ArtsTec - Free printing (in class)
HIB335 lab - Free printing in class.
HIB 3rd floor general - copy card.
All Libraries i believe use the Copy card / print retreval system
Student workers generally have access to printing from their jobs (those in Admin bldg, student center, etc)
there are a lot more shool computer labs that have printers - printing is restricted though depending on the school and which class your in..
but yea.. basically bring your own paper or something like 10cent a page.
Mrsbugi - 15c at USC? Ouch... they know your rich (or academically endowed with scholarships.. at least you better be) so they ream you on tuition and printing
