the printer. Baud is a unit of transmission speed based upon the number of signals
per second. The computer and the printer must be configured at the same baud rate
for the communication to function correctly.

BIDIRECTIONAL PRINTING

The print head moves from left to right on one line and from right to left on the next
line. In this way, the speed of printing is optimized.
BIT

CHARACTER SET
A set containing related characters. A set, for example, may be composed of math

Printing is considered compressed when the horizontal spacing is set to 17 cpi
(characters per inch).
