We ran tests on text in different font sizes, from 2 to 72 points. What was interesting is that our main observation was that in this area, inkjets are not yet up to the level of laser printers. Certain models, like the Lexmark Z816, produce totally illegible text when printing 2-point fonts. With larger font sizes, you can also see that characters tend to bleed slightly and that the printers have trouble rendering smooth curves. The differences among the models we tested were relatively slight.
