only have experience of one or perhaps two printer. We can say that in our experience Printer x is a dog or brilliant.
Cost per page: £1 per 100 pages is saved if the ink works out 1p cheaper.
There are printers out there with a print cost of 8p per page and others at 2p per page. I leave you to work out how you would rather spend your money. The more expensive ones are frequently faster and quieter as well.
ps. The fewer ink tanks you have the more you throw away every time one colour runs out!
