n Proportional printing
Have you ever looked closely at the printing books and magazines? Doesn’t it look nice? The main reason is that each character is given an amount of space proportional to its actual width. A typewriter (and most printers), on the other hand, give every character the same amount of space, no matter how wide it is. (Pica pitch, for example, gives a “w” and an “i” l/l0 of an inch each. Looking at these letters you see that a “w” is two or three times as wide as an “i”.)
