Lexmark and HP have the print head in the cartridge, which makes makers original cartridges very expensive. Refilled cartridges from Choice (click here) are very good and much cheaper. This has the advantage that when you fit a new cartridge you have a new print head - or a cleaned and tested one in a refilled cartridge. Epson and Canon printers have the print head built into the printer, so if the printer isn't used for a long time the head can clog. In an Epson replacing the print head would generally cost more than a new printer and so would be uneconomical. I have just bought a Canon MP600R. This has the printhead in the printer, but it's an easily replaceable item (about £45). The MP600R is expensive as inkjet MFDs go (about £150) but it's a superb machine wireless, quiet, fast, duplex and excellent copying quality. I have always considered Lexmark to be cheap and poorly built.
