InkJet Printers Lying, Or Just Wrong?
akkarin writes in about a study reported at Ars Technica on how accurate ink-jet printers are when they report that cartridges are empty. Not very, it turns out. Epson came out on top of the study (and Ars rightly questions how objective it was, given that Epson paid for it), but even they waste 20% of the ink if users take the printers' word for when to get a new cartridge. On average, the printers in the study wasted more than half the ink that users bought.
There's actually a free software that's available that can be used to reset the chips in several brands of ink cartridges. I'm not sure if you need any type of hardware, but I've heard good things about it.
It allows you to reset the numbers and use the remainder of the ink, before it makes you replace it.
If you ask me, the feature that stops you from using a cartridge after the ink is too low, is pretty ignorant. I think it's obvious when the ink is completely out, so why not let the user decide?

Yes.
I've found 'extra' ink in both my Epson and HP inkjet printers. I'd use refill kits, but the cartridges tend to leak over time, and refilling takes a lot of time and effort. In the meantime, for Epson printers, just go with the el cheapo compatible cartridges from places like Inkco. Epson C88 cartridges are $5 a pieces, as opposed to to ~$25 for branded cartridges.

I've been a long time fan of Canon photo printers, in fact I just bought a Pixma Pro9000. Their ink tanks are clear so if you doubt what the printer is saying you can eyeball it for yourself. So far it's been very accurate about remaining ink level.
I used to work at an outsourced call centre, supporting Epson printers and scanners. By far the biggest customer complaints we received always had to do with printers wasting ink.
During our training, and from talking to various Epson reps, we learned that the printer doesn't actually monitor the amount of ink in each cartridge. Rather, it estimates the amount left, based on the various print settings chosen.
The worst part is that on many printers, once it "thinks" it's out of ink, it will no longer print until you change the cartridge. In some older printers, you could simply remove the cartride and then put it back into place, tricking it into thinking you replaced it with a new cartridge. However, this would make the ink monitor even less accurate. Newer printers won't even allow this, because the circuitry on the cartridge itself will lock you out once it has reached the estimated empty level.
There are some tools available that let you reset the "intelligent cartridges" so that they can be refilled and reused, but of course they aren't supported by Epson and may void your warranty.
I've got a Canon S750, and it is great on reporting ink levels. It also has three separate color cartridges, which is nice. There have a been a few times when it was over zealous in reporting low ink, but all I had to do was take the cartridge out and put it back in and it ran fine until it was actually out of ink.

We use Epson inkjet receipt printers at my hardware store and we put a small piece of masking tape over the cartridge ink window. We find that we get an extra week or two of use out of a cartridge by covering the ink window. When the ink runs out (i.e. the receipt is blank) we swap the cartridge.

One of the biggest problem I have with lasers, aside from photo quality, is that paper handling isn't so good as compared to an inkjet. Inkjets can print on a variety of different media - envelopes, glossy photo paper, card stock, etc. Most inexpensive lasers have very poor paper handling in that they have an inability to print on anything thicker than thick bond or thin card stock. More expensive printers have no problem, but then they are not cost competitive with an inkjet.
Also, cheap lasers tend to wear out quicker than inkjets, in my experience.

In case there are any young ones around, a color HP printer in 1996 was $200 something. Ink was $15 for black and $15 for color so $30 and it lasted for my use over a year. Color was a novelty then too so that was impressive for the amount of waste I went through.
Today you can get a printer for under $100 and EACH color is $15 and it lasts 3 months.
if you steal from one source, that is plagiarism, if you steal from many, well, that's just research.
Kodak has a line of full-size inkjet printers. They charge a bit more for the printer ($150 for a pretty standard multifunction with 6 colors), but the cartridge costs are MUCH cheaper. $10 for black that is supposed to last ~300 pages of full text, and $15 for a 5-color cartridge. Or you can buy them together for $22.
