auto line feed
When this option is turned on in the default-setting mode, each carriage return
(CR) code is automatically followed by a line feed (LF) code.
bidirectional printing
Printing in which the print head prints in both directions (bidirectionally) from
left to right and then right to left. This increases the print speed but may reduce
precise vertical alignment. See also unidirectional printing.
character table
A collection of letters, numbers, and symbols that provides you with the set of
characters used in a particular language.
characters per inch (cpi)
The number of characters that can fit in one inch of a text line, determined by the
size of the characters. See also pitch.
compress printing
This function reduces the size of the data. You can compress your printing data
to the ratio of 75%.
control codes
Special codes used to control printer functions, such as a carriage return or line
feed, instead of printing characters.
cpi
See characters per inch (cpi).
default
Value settings that take effect when a device (such as a printer) is turned on, reset,
or initialized.
dithering
A half toning method in which dots are printed in a predetermined pattern to
simulate a shade or tone. Dithering works best for images with solid colors, such
as charts and graphs. See also half toning.
dot matrix
A method of printing in which each letter or symbol is formed by a pattern
(matrix) of individual dots.
