I have the exact same problem as you! I swear I print like 5 bajillion pages a year. I'm my own deforesting factory in my dorm room. Haha.
So I've come up with some methods.
I always print using the fast draft setting when what I'm printing is all text (pictures and diagrams usually need higher quality settings). This saves ink, because the printer deposits less ink on lower quality settings. Also, as an extra, my printer also has this setting where you can adjust how dark the ink is (how much ink is deposited - if the printout is light or dark) - these two put together make it so that I only have to buy new ink once a quarter. I wonder if printing in grey saves ink? hmmm.
Also, I print in grayscale to save ink, because black ink is cheaper. And I get my ink cartridges refilled at Walgreen's (or just refilled period) because that's cheaper too.
Other places to print:
1. Work. Like someone else said, print things at work.
2. Niches. Find the niches on campus where there is free printing. At UCLA, for example, there's this student activities center where you can print 10 pages for free (but nobody is counting), so I'll print a few pages there every once in a while.
3. Lab classes. Then, there are lab classes that I have. All labs have free printing, so I just print stuff there too. But do it when your TA isn't looking, or go to the classroom after hours and use the printer lol. Unless your TA is a grad student who is cool and won't care.
4. Lab you work for. I also print at the lab I work for, but! This is different than printing at work. Since I usually don't have stuff to print at the lab I work for, my coworkers get suspicious when suddenly I start picking up 100s of papers out of the printer. So what I do is, I sometimes work late nights or weekends when nobody else is there, so I do all my printing at once then. I'll print an entire quarter's worth of papers when nobody is looking. It's not stealing (I mean, everyone else prints, that's what printers are for), it's just a way of protecting my reputation at the lab (so that I don't become the undergrad who mooches all our ink! haha)
5. Ask around and find out where cheap printing is.
Also, to save paper, which gets expensive, print on both sides. Save bad printouts, and papers you don't use anymore (like last quarter's one-sided printouts) and use those as scratch paper to print on.
haha.
