I stopped buying cartridge-based inkjets years ago. I'm happy with my Canon G3020, which uses ink tanks (built into the printer, not a third-party addon that the manufacturer will claim voids the warranty).

And it's impressive how long those ink tanks last: I printed out 400 pages of full color and the ink tanks went from 80% full to about 50% full. (There's a clear plastic window in front of the ink tanks, with a "refill when ink reaches this level" line on it — a raised line of plastic, not something inked or painted onto it that could rub off — so you can glance at the printer and see what level the ink is at). The ink bottles cost me about $12 each if I remember right, and each one will fill the ink tank from the "refill here" line to more than 100%: I had to stop filling, then wait until I had printed a few hundred more pages, then refill the rest. Rough back-of-the-envelope math says maybe 1200 pages from a full ink tank. The C, M, and Y bottles will cost $36 total (the K bottle will last a lot longer so I'm not counting it in this math), which means 3 cents a page for full-color, ink covering nearly the whole page, prints. Considering the cheapest print shop I've found would charge me 20 cents per page (and I've seen 50-cents-a-page quotes for full-color printing), the $200 printer will have already paid for itself by the time you run through one ink tank (17 cents saved times 1200 pages is $204).

This is turning into an ad for Canon, but seriously, it's a great printer. The only thing I don't like about it is that it doesn't do automatic duplex printing (I have to pull the pages out, flip them over, and put them back in), and I knew that when I bought it (the model that did automatic duplex was $450, and I chose not to buy that one). Oh, and I am not affiliated with Canon in any way: considering how glowing a review this is, I should probably say that explicitly.

But the best part for me was that it's not an Epson. I previously owned an Epson ink tank printer, and it was great... until the ink sponge filled up. Did you know that ink jet printers, at least the ink-tank variety, have a sponge inside them? When you do a "clean clogged print heads" routine, the printer moves the print head over to the position of the sponge, and pushes ink through the print heads until it's moved enough liquid to hopefully push the clog out. Sometimes it works, sometimes it doesn't. But the sponge can only absorb so much ink before it fills up. And on an Epson, the sponge is not a user-serviceable part. They want you to send it to one of their official repair shops to get it replaced, costing I don't know how much because I refused to do it. I found an unofficial way to wipe the printer's internal counter that kept track of how much ink was in the sponge... and when the printer died about a year later (for unrelated reasons), I went shopping for another brand. I'll never buy an Epson printer again. Canon, on the other hand, will sell you a "maintenance cartridge" (a large sponge mounted in a plastic tray of the right shape to slot into the printer) for about $10 plus shipping. When the sponge gets full you can just swap in a new one. Dead simple.

Enough gushing from me. The point that I spent way too long getting to is, ink-jet printers don't have to use cartridges. Ink-tank printers used to only be available in the Asia/Pacific market, but they're available in the US now. A couple years ago I helped my parents (in the US) buy a Canon G3020 and set it up for them. So far their experience has been positive, too.
