B
A unit of speed that measures the rate at which
information is transferred. Baud rate is the reciprocal of
the length in seconds of the shortest pulse used to
carry data. For example, a system in which the shortest
pulse is 1/1200 second operates at 1200 baud. On RS-
232 serial lines, the baud rate equals the data flow rate
in bits per second (bps). To communicate properly, a
printer must be configured to operate at the same baud
rate as its host computer.
A typeface with a heavy line thickness produced by a
double strike print method. See also character weight.
Compare with shadow printing.
A reserved area in printer memory that data is written to
and read from during data transfers.
