A.2 Macro Numbers
The macro feature is a selection of the INITIAL menu. Table 2–3 and
Section 2.10 provide a brief description of the macro feature. Press
Reset
to
invoke the macro number.
The macro feature allows you to select an environment for local compatibility.
It assigns the proper user preference character set, enables/disables the
initialization message, and specifies the return response (device identification)
when a Device Attributes (DA) request is received. The macro feature is
slightly different from other menu features because three parameters (user
preference character set, initialization message, and device ID) are
added
together
to determine the macro value. The user preference, initialization
message, and device ID values cannot be selected independently; they must be
added together to form the macro value.
The macro feature allows you to choose the user preference character set
appropriate for your application or system. Consult the
Digital ANSI-
Compliant Printing Protocol Level 3 Programming Reference Manual
for more
information about the user preference sets. Table A–2 lists the user preference
character sets and their values.
