Gotcha, I get it now. Sometimes it just doesn't click.
I forgot the model I had, but I picked it up on sale for $25 because they used the same printers at my mom's work. She'd nix a new black and color ink every month or so and we had a nice little collection going. I would go through 3 black inks in a typical semester.
When she didn't have that job anymore, and I ran out, I went price hunting. Cheapest I could find was $50 per ink. Paying that every month and a half on my budget? I'd rather pay a lot up front and save even more later.
Edit: My printer was similar to this one, except it's gray with black detail...same kind of thing though. Basic inkjet.
