- adrian_b 1y agoFor printing photos, you are right that a 300 ppi printer is better than an 1200 dpi printer. On the other hand, for printing text, an 1200 dpi printer has the quality of an 1200 ppi printer. Many well-designed traditional typefaces have relied on optical effects caused by details that require for being printed a resolution higher than that at which the human eye can distinguish a set of bars from an uniform background (which is the object of TFA). For instance, in some typefaces the edges of the strokes are concave or convex, not straight, which could be rendered in a computer display only by either a much higher resolution or by more sophisticated pixel preprocessing methods (in order to simulate the effect on the eye). Whenever such typefaces are displayed at a lower resolution, i.e. on computer monitors, they are very noticeably uglier than when printed on paper by traditional metal printing methods or even by a high-resolution laser printer.
