Control Codes
Journal mode
Journal mode is a station select command. All data sent to the printer, following the journal mode select command, is stored in the EJ as a single record. Any control commands sent to the electronic journal will end the journal entry. An EOT, NUL or any printer command will end journal mode. Typically an EOT, CAN or station select will be used to end the journal mode.

Description The function enters journal mode. When in journal mode, commands are parsed and any command that is not appropriate is removed, causes journal mode to exit, or is saved.
In general commands to involve printer operation are ignored, Commands that will cause a basic change in the printer like the [ESC]@ Initialize printer command stop the journal entry. Commands that return a response from the printer are not placed in the journal.
All other commands are placed in the journal, and will be processed when the journal is printed.
The [EOT] (4 or 4H) and CAN (24 or 14H) will cause the journal to stop and will not be processed again.
In typical operation, a station select command should be used to exit journal mode. Note that any station select including another Journal select will close the journal entry. If a Journal select is processed in Journal mode, the current record will be closed, and a new record opened.
