CORRESPONDENCE QUALITY AND
DATA PROCESSING PRINTING
When you turn on your printer, it's
automatically
set for
data processing printing. This is a high-speed (160 characters
per second) mode which prints bidirectionally
-
first line
prints left to right, second line prints right to left, etc. This is
handy for program listings and high-volume printing.
For important documents and letters, use OKI DAT A's
special correspondence quality printing. This mode prints at
40 characters per second in two passes; the second pass fills
in the dot pattern to form a sharp, crisp letter. It's ideal for
word processing packages.
