define a limited number of custom characters and define a macro. These
character/macro definitions can also be saved in user store. However, only one
character definition and one macro can be active at any time. One macro and one user-
defined character definition can be flagged to load and run at startup. If a flag is set, the
printer will automatically process the macro and/or load the user-defined character set at
initialization.
Because user store is intended to be loaded only a few times and then printed as part of
normal operation, the programmer must take some care during the definition phase.
The programmer must assume the responsibility to assure the 16K buffer size is not
exceeded. User store can save macros and user-defined character sets.
When the basic user store is full, it can be moved to extended user store. Individual
items in the extended user store can not be erased. The entire extended user store must
be erased all at once. You may place two items in user store with the same name and
the last defined item will be used.
Defining Macros
Macros can be defined two ways. The first is by using the begin and end named macro
commands. These commands start the recording process and automatically save the
macro when it is complete. The macro data is not processed, as it is sent to the printer.
Function Begin named macro record
ASCII [ESC] [US] b <Name..> <0>
Then send the data to be recorded. The printer does not process the
data. The terminating <0> may be replaced with an & or redefined. See
[ESC] [EM]T<n> or &%UT<n> on page 128.
Function End name macro record
ASCII [ESC] [US] e <Name..> <0>
The second way to define macros is to use [ESC] g commands to define
the macro, and then the save macro data command to save the data.
The terminating <0> may be replaced with an & or redefined. See [ESC]
[EM]T<n> or &%UT<n> on page 128.
Function Start macro record
ASCII [ESC] g <1>Then send the data to be recorded. (The data is processed
and printed).
Function Stop macro record
ASCII [ESC] g <2>Then save the macro.
Function Save macro data
ASCII [ESC] [US] m <Name..><0>
Saving User-defined Characters. To save user-defined characters, first
define the character set.
