The horizontal location on the paper where the next character will
print.
active line
The vertical location on the paper where the next character will print.

ASCII
Abbrev. for American Standard Code for Information Interchange.
A standard character encoding scheme introduced in 1963 and
used widely on many computers and printers. It is a 7-bit code
with 128 different bit patterns. There is no parity
recommendation.
attributes, print
Operations performed on text that alter its appearance but do not
change the font. Examples: underlining, superscripting, bold, etc.
B
bar code
A printed code consisting of parallel bars of varied width and
spacing and designed to be read by a one-dimensional scanning
device.
baud
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.
bold
A print attribute specifying text of a heavy line thickness.
See also character weight.
buffer
A reserved area in memory where data is written and read during
data transfers.
bus
A circuit for the transfer of data or electrical signals between two
devices.
