Datamax DGL - Manual (Page 41)

Module Operations:
DGL will emulate 2 different Modules: Ram and Flash. Datamax has several
Flash and Ram modules, but DGL will map all Flash modules to the same
PTX Flash File System, and all Ram Modules to the global Memory Pool.
When recalling something from a module, the Module Identifier is not
specified in the command, so this should not cause a problem when DGL
maps them to a single Flash / Ram module.
The only problem that might occur is when there is bi-directional
communication needed for a Windows driver, which might verify an object got
stored correctly by requesting a module directory.
When specifying a module that is not available, the printer will automatically
select the default module.
Bi-Directional Communications
Bi-Directional communications can be divided in two groups: time-critical
(immediate), and non-time-critical responses.
Datamax describes the time critical responses as follows:
When the printer receives a Status and Control Command, its current
operation will be momentarily interrupted to respond to the command. Status
and Control Commands may be issued before or after System-Level
Commands; however, they cannot be issued among (a) Label-Formatting
Commands, (b) during font downloading, or (c) during image downloading.
Commands that require immediate action (including commands that request
immediate response) will not be supported.
Non time-critical responses are supported by DGL. For example the feedback
or memory module information request commands.
Cutter Commands
The Commands to activate the Cutter (System Level Command <STX>o, and
Label Formatting Commands ‘ c’ and ‘:’) are only processed when the Media
Handling menu is set to ‘Cut’, and the DGL Advanced-User Menu ‘Cut Cmds’
is set to ‘Process’.
