Why are low dpi printers more expensive?

I'm looking to buy a new photo printer for my Canon 10d digital
camera.

I want an Epson printer because the carts are cheap and the printers
last a long time.

Just one thing, I've seen DPI on the new and old printers and I can't
understand why the low dpi printers cost more momey.

For example, Epson Stylus Photo 2100 is 2880 DPI on A3 paper and costs
around £422. The Epson Stylus Photo R800 is 5760 DPI on A4 paper and
costs £240. There are other printers aswell which are like this, low
DPI more money, high DPI less money.

From what I understand, "The resolution is stated in pixels (points)
per inch. The higher resolution the finer printouts."

Why is the higher DPI printer/s cheaper than the semi professional
Photo printers? I really can't understand.

I know photo paper can only handle so many DPI before it starts to
overlap but why are the low DPI A3 printers so much more money?

I don't think A3 printers can print more DPI on A4 paper.



Epson 2100 is a wide-format printer, R800 prints up to A4/8.5" x 11". Look
at the size of the printer first.
