CT_CLOSE: This command will power down the
reader and turn off the red LED on the
smartcard module. This command
should be used after communicating to
the card with the CT_DATA command.

as the printer configures itself for pass-
through mode. The messages printed
relate to port parameters for the internal
communication port communicating with

will also print out when the printer has
been taken out of pass-through mode.
Once in ‘pass-through’ mode, no debug
messages are printed.
