Magnetic Card Reader (MCR) Command
This command can be used to configure and activate the
Magnetic Card Reader (MCR). The MCR command will
be ignored by printers not equipped with a Magnetic Card
Reader.
The MCR command can be issued in a label file (! 0
200 … PRINT), or in a utilities command session (!
UTILITIES … PRINT). This command activates the
MCR. When the printer is turned on , the MCR is not
active by default until the MCR command is received. To
make the MCR active on power-up, the MCR command
can be issued from autoexec.bat or run.bat files.
The RXD LED of the printer will blink while the MCR is
active. When the MCR times out or after a successful
read (provided the MCR is not in MULTIPLE read mode,)
the MCR will deactivate, thereby returning the RXD LED
back to its normal state.
