Subject: Re: "em" should be horizontal, "ex" vertical

   Vaguely related trivia:

   Anyone who's used a typewriter more than occasionally knows there are
   two basic types: pica and elite. Pica is 10 characters per horizontal
   inch and 6 lines per vertical inch, Elite is 12 characters per
   horizontal inch and seven lines per vertical inch. (There's also a 15
   character per inch typewriter; can't remember what it's called.)

The Apple Imagewrite II manual I have lists escape sequences for
selecting various sizes; 9 cpi is called extended, 13.4 cpi is called
semicondensed; 15 cpi is condensed, and 17 cpi is ultracondensed.
this printer can be set to either 6 lines per in or 8 lines per
inch; no names are given for the line spacing.
