Control Characters
Any character that causes the printer to perform a function is classified
as a control character. Note that, although the Cl control characters are
available in one of the standard character sets (ISO 8859/Multinational),
your printer does not implement them.
American National Standard ANSI X3.4 and International Standard
ISO 646 define the C0 control characters based on the specific
function performed by the character. The C0 control characters are
divided into the following categories.
q Communication controls - Control characters intended to control
or enable data transmissions over communication networks.
q Format effectors - Control characters that control the layout or
position of information on the printed page.
q Information separators - Control characters that separate and
qualify information in a logical sense.
q Miscellaneous control characters - Control characters whose
definitions preclude their inclusion in the preceding categories.
The following table lists and defines the original use of the C0
control characters.
Note: The functions of the control characters can vary from one
emulation mode to another. Therefore, these descriptions are included
in Chapters 4 through 9.
