D Glossary

	A
active column	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.
active position	The position on the paper where the next character will
	print. The intersection of the active column and the active
	line.
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.
