	O
OCR	Abbrev. for optical character recognition. A process by
	which a machine can “read” characters printed in a
	special standardized font. Data are read by a
	photoelectric optical scanner and can be recorded on
	magnetic tape or disk. OCR-A and OCR-B are two widely
	used OCR fonts.
	P
parity (check)	Parity checking is the addition of non-data bits to data,
	resulting in the number of bits that are set to a “1” being
	either always even or always odd. Parity is used to detect
	data errors.
PCBA	Abbrev. for printed circuit board assembly.
pica	A name indicating a monospaced font with a pitch of 10
	cpi (and usually 12 points in height). Pica is also used in
	typography as a unit of measurement equal to 1/6 inch.
pin configuration	Establishes the physical attachment and protocol
	conversion connections for the host interface.
pitch	The number of text characters printed per horizontal inch.

	information between computer systems, or between a
	printer and a host computer. For computer printers, a
	protocol is the coding convention used to convey and
	print data. A printer protocol includes codes for printing
	text and graphics, as well as codes instructing the printer
	to perform special operations, and machine-to-machine
	communication codes.
	See also compatibility and emulation.
