■Proportional printing

Have you ever looked closely at the printingin books and magazines? Doesn’t it look nice? The main reason is that each character is givenan 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” 1/10 of an inch each. Looking at these letters you see that a “w” is two or three times as wide as an “i”.)

Well, you too can enjoy professional-looking proportional printing. You can turn proportional printing on and off with the following commands.
