The reality is that all-in-ones are always a compromise. They do a lot of things well but not one single thing great. Some printers can do double duty as photo printers and document printers. If you are concerned about the cost of ink to the point where you want to go to the trouble of calculating the cost of ink per print (a laborious process fraught with variables) then you may not want to be using a great photo printer to print out text documents. That is the economics of the situation. My view is that if you enjoy printing your own photos at home and having that convenience you should probably invest in a good photo printer dedicated for print making and buy a second low cost printer for everyday home office use. This way you can anticipate your ink costs of the long haul and if you still want to calculate your cost per print you don't have the occasional text document skewing your sample data.
