Hex Transfer
The Hex Transfer feature allows the user to send PCL escape sequence printer commands
to the printer with simple text strings. You may send any valid command or string of
commands with no limit on the length or complexity. Form macros, signatures, or simple
commands may be passed through any platform to the printer since they are simple text.
The printer will convert them back to ESC (escape) sequences when they arrive at the
printer. Hex Transfer is automatically enabled while in MICR Mode. To enable it for all
applications use the following commands:
Turning Hex Transfer On
To enable Hex Transfer, send the following command:
&&??&%
Once Hex Transfer is enabled, the character sequence &% will act as a trigger sequence.
Any data following these trigger characters will not be printed and will be treated as Hex
Transfer data until the Hex Transfer ending character $ is encountered.
Turning Hex Transfer Off
To turn Hex Transfer off, send the following command:
&&??!!
This command will clear the trigger sequence and allow the &% characters to print. This
clear command may be sent at any time to assure that Hex Transfer is disabled. When
MICR Mode is entered, Hex Transfer will automatically be turned on, and when MICR
Mode is exited, Hex Transfer will be turned off unless it has previously been activated
outside of MICR Mode with the &&??&% string.
