I absolutely adore this printer.
http://www.canon.ca/english/index-pr...20&gid=2&ovr=1 (About $100 - On sale for 80ish occasionally)
I wanted a printer that would print, be easy on the ink and I didn't need a scanner or fax so this was perfect.
It automatically double sides, too. I pretty much print lecture notes and I go through about 3 stacks (1500 pages - probably closer to 2500 b/c of the double siding) of paper a year on one tank of each colour (I actually have colour ink left after the year). I just turn down the amount of ink the printer uses in the settings.
I also purchased a warranty b/c I had a friend who worked at Staples and he told me that when I run out of ink, just come in and say the printer is busted for w/e reason. You get a new printer (which has all the ink included) and you have the option of paying for a new warranty or just eating the $20 for ALL the ink and a new printer. Yes, a tad unethical, and yes a tad inconvenient, but to drop a couple of $100 on ink is just crazy. Tried it once it worked for me :P
