character graphic. The visual representation of a
character,defined by toned or untoned picture
elements (pels). An untoned pel (a reversecharacter) is
visually represented by the toned pels around it.
character increment. The distance the current print
position is increased by printing the current character

code page. Afont component that associates code
points and character identifiers. Acode page also
identifies how undefined code points are handled.
code point. A1-byte code that represents one of 256
potential characters.
continuous-forms paper. Aseries of connected forms
that feed continuously through a printer.The
connection between the sheets is perforated to allow
the user to tear them apart. Before printing, the sheets
are folded in a stacked arrangement, with the folds
along the perforations. (Note that some continuous
forms are in rolls and are not folded.) Contrast with
cut-sheet paper.
copy. Thespecification level of an APU print
definition where most layout work, such as specifying
page layout options, selecting and placing images, and
defining constants and boxes, is done.
cut-sheet paper. Paperthat is cut into separate sheets
before being printed on. Contrast with
continuous-forms paper.
D

direction controls on a page is the hardwareorigin.
Secondary and tertiary reference points are possible as
well, allowing more than one print direction on a page.
duplex printing. Pertaining to printing on both sides
of a sheet of paper.Contrast with simplex printing.
E

font administrator. Aperson who is responsible for
installing and maintaining the fonts that are stored in

font metrics. Measurement information that defines
individual character values such as height, width, and
space as well as overall font values such as the average
and maximum heights and widths of characters. Font
metrics can be expressed in specified fixed units, such
as pels, or in relative units that are independent of both
the resolution and size of the font.
form. (1) The paper on which output data is printed
by a line printer or a page printer.(2) A physical sheet
of paper.See preprinted form.
form definition. Aresource that defines the
characteristics of the form which include overlays to be

data on the form, and the number and modifications of
