PC World checked out the PhotoSmart 8250 printer from HP, here's a quote from their evaluation:

The silver-colored, $200 Photosmart 8250 marks a departure for HP printers. For one, cartridges for previous models contained up to three inks, whereas the 8250's six cartridges contain just one ink each. Also, the older cartridges incorporate a print head, but the 8250's cartridges don't have built-in nozzles because the printer has a permanent print head. In contrast, the $149 HP Photosmart 8050, which we also tested this month, uses multi-ink cartridges.
