all points addressable (APA). The ability to address,
reference, and position text, overlays, and images at
any defined position or pel on the printable area of the
paper.This capability depends on the ability of the
hardware to address and to display each picture
element.

medium from more than one source (bin).
APA. Allpoints addressable.

BBar Code Object Content Architecture (BCOCA). An
architected collection of constructs used to interchange
and present bar code data.
bar code symbology. Abar code language. Bar code
symbologies are defined and controlled by various
industry groups and standards organizations. Bar code
symbologies are described in the public domain bar
code specifications. Synonymous with symbology.
baseline. The imaginary line on which successive
characters are aligned in the inline direction.
BCOCA. See Bar Code Object Content Architecture.
bin. Apaper source on cut-sheet printers. See also
cassette.
bounded-box font. A font designed to use bounded
character boxes. Contrast with unbounded-box font.
BTS. Burster-trimmer-stacker.
burst. Toseparate continuous-forms paper into single
sheets.
burster-trimmer-stacker (BTS). A printer hardware
feature that separates continuous forms into single
sheets, trims the carrier strip from both edges of the
forms, and stacks the sheets.
Ccassette. In a cut-sheet printer,a movable paper
storage enclosure. See also bin.
CCITT. SeeInternational Telegraph and Telephone
Consultative Committee.
changeable media origin. The ability of the printer to
accept a command that changes the point on the
medium where printing begins.
channel-attached. In PSF,a device that is linked to
the host system using only S/390 channel protocols. For
example, a 3800 printer cabled to the host system with
a S/390 channel adapter is considered a
channel-attached printer.Contrast with SNA-attached.
character. (1)A member of a set of elements used for
the representation, organization, or control of data.
Characters may be letters, digits, punctuation marks, or
other symbols represented in the form of a spatial
arrangement of adjacent or connected strokes or in the
form of other physical conditions in data media. (2)A
letter,numeral, punctuation mark, or special graphic
used for the production of text. (3) In bar codes, a
single group of bars and spaces that represent an
individual number,letter, punctuation mark, or other
symbol. (4)A byte of data. (5) See alsographic
character.
character graphic. See also graphic character.
character graphic. A visual representation of a
character,other than a control character, that is
normally produced by writing, printing, or displaying. (T)
character identifier. The standard identifier for a
character regardless of its style. For example, all
uppercaseAs have the same character identifier.
character rotation. The alignment of a character with
respect to its character baseline, measured in degrees
in a clockwise direction. Examples are 0°,90°, 180°,
and 270°Zero-degree character rotation exists when a
character is in its customary alignment with the
baseline.
character set. (1) A finite set of different graphic or
control characters upon which agreement has been
reached and that is considered complete for some
purpose; for example, each of the characters in ISO
Standard 646 7–bit Coded Character Sets for
Information Processing Interchange. (2) For page
printers, the font library member that contains the
character graphics and their descriptions.
code page. A set of assignments, each of which
assigns a code point to a character.Each code page
has a unique name or identifier.Within a given code
page, a code point is assigned to one character.More
