The High Price Of Ink Cartridges - Frugality

What is the true cost of ownership of a color printer?
The true cost of ownership of a color printer is a topic that the printer manufacturers do not explain or make easy to understand. In fact by looking into this topic I found that it seems to almost be purposely misleading. The rule of thumb is that the cheaper the printer, the more expensive the disposable costs for refills and so on.

Lets look at this example of a $55 inkjet model with black ink costing $19. But with a yield of 170 pages per cartridge:

Seven pages a day (very conservative amount) times 300 days equals 2,100 pages -- an ink bill of $235.60 per year. If you own the printer for three years, the cost of cartridges comes to more than $700 or about 13 times the original cost of the printer.

Let's say you print 50 pages a day, 300 days a year. Using the above example, that equates to printing 15,000 pages annually. At that same rate, your annual ink cartridge bill would total nearly $1600.00

Now let's look at a Brother HL-2270 mono laser printer model that costs $149.00 with ink (toner) costing $78 with a yield of 2700 pages per cartridge:

Seven pages a day (very conservative amount) times 300 days equals 2,100 pages -- an ink bill of $60.06 per year. If you own the printer for three years, the cost of cartridges comes to $180.18 just slightly higher than the original cost of the printer.

Let's say you print 50 pages a day, 300 days a year. Using the above example, that equates to printing 15,000 pages annually. At that same rate, your annual ink cartridge bill would total just over $400.00.

Inkjet Printer Plus Cost Of Ink For One Year At 7 Pages Per Day: $285
Laser Printer Plus Cost Of Ink For One Year At 7 Pages Per Day:$227

Inkjet Printer Plus Cost Of Ink For One Year At 50 Pages Per Day:$1655
Laser Printer Plus Cost Of Ink For One Year At 50 Pages Per Day:$549 (LOOK AT THE DIFFERENCE)

And it isn't just cost that conspires against ink jets. They usually won't print pages as fast as laser printers, although some recent high-end models are catching up. Inkjet cartridge printers can also be a major hassle generally having more problems. The statistics indicate that inkjet printers are inundated with cartridge-error messages when the cartridges are perfectly fine, or have the machine suddenly go crazy and spit out meaningless characters or text in an endless stream. The inkjet printers are also set up in a way that makes it difficult to minimize the amount of ink they use. It appears they're designed to make you use more ink than you need to with no way to default to "draft quality" just offering a "speed quality".

But this still doesn't fully answer my question. How can I save money on the printers I currently have? One inkjet and one laser printer.
