I bought an Epson inktank inkjet b&w printer a few months ago. This thing is a beauty. Printing cost is ridiculously low , way lower than with a laser printer. A bottle of ink costs €10 and lasts for 12k pages. Sure, the speed is nowhere near that of a laser and neither is the functionality, but that just doesn't matter if you can print a 200 page document with less than €1 including the paper.
I had one of those too, and it worked great for about 6 months, until one of the print nozzles became clogged. It turns out that on most printers, the print heads are part of the cartridges (=replaceable), but on the ecotank printers they're built-in to the printer - so if the printer's built-in cleaning system doesn't work, it's almost impossible to unclog.
