I am using 1998 lexmark 5700 ($50) which has an optional 6 color mode. Two cart with 3 inks each. I am refilling now and this 6 ink mode is much better then the standard 4 color mode. Photos done the 4 color mode on glossy paper show the ink dots when examined closely , done in 6 color mode on glossy the dots are not visible, it really does like a film print.
I guess these days there are printer which can do a good job in 4 color mode. But the paper does matter.
Also be careful about the ink costs. Decide if you are willing to refill or not. Then choose a printer with either cheaper ink per page costs when buying a cart or easier refilling procedures.
The lexmark line seems to be geared toward low printer, but the highest cart costs. They have new line with smaller cart at the same price.
There is consumer’s magazine in store (now?) with an article about inkjet costs and Quality for the current printers.
A photo print looks good when the printer is able to print at least 250-300 dots per inch. (real not advertised) Less then 250 starts to make it a visibly fuzzy, more then 350 is resolution not causally visible when handling a photo at normal distances. Again paper matters with the various coated (glossy) papers able to control the dot of ink as it hits the paper soaks in a tiny bit to allow drying but fully covers the white (fibers) of the paper to convey the right color. Hence the Manufacturer with their branded inks and paper at their price.
