Character Size
In addition to the basic cpi spacings and proportional spacing, the
printer offers three other modes that can change the size of your
printing. These modes are double-wide, double-high, and
condensed.
The double-wide mode doubles the width of any size character,
while the double-high mode doubles the height of any size
character. These modes are useful for emphasizing document titles
and headings in reports, but are usually not suitable for large
amounts of text. These modes can also be combined to obtain even
more impressive printing results.
