Also the integrated scanner worked out-of-the box for me under Debian, after I compiled and installed utsushi [1] from sources (edit: I'm only scanning from the utsushi command-line, no experience WRT integration with sane etc.).
I was at the point of swearing never to buy Epson inkjets, or any inkjet again. Then they released the eco-tank. I reluctantly made the purchase, almost expecting to be let down, but glad to say all is well.
The comedian Jimeoin even did a TV ad for the eco-tank range (here in Australia at least). It became a worldwide joke about tossing out printers when ink ran out. Maybe that's why they chose him for the eco-tank campaign.
The HP inkjet "plotter" works by rasterizing the plot in the host computer's memory and then sending strips of raster to the plotter. The dot resolution of the print head (replaceable, but not part of the ink system) matches the 0.7mm resolution of the pen plotters it replaced.
Inkjet technology is fine, it was the exploitation of it by HP which lead to copy cats that really made it ridiculous.
I've got an HP inkjet wide format plotter (36" wide) that was built both before HP was all in on ink as a profit center and built by a different division (plotter division). It has been a reliable workhorse for over 20 years now and while I don't use HP ink any more (they don't sell it) third party ink works fine.
I replaced my desktop printer with an Epson Eco-tank printer. They claim it comes with 2 years of ink (at my rate that is probably 4 years :-) and they the ink is not expensive. So there are people trying this model of "let's not bother screwing people on ink" and I'm trying to reward them by buying their printer.
