USB Class B connector
USB Interface
The printer has a socket on the CPU board for connecting a bar
code wand or scanner. The socket is accessible through a slot in
the printer's rear plate.
If a Code 128 bar code that contains the character FNC3 is read
via this port, the data will be treated as a setup string and will
change the printer's setup accordingly. A setup bar code may
contain a single parameter or a combination of up to 3 or 4 setup
parameters. Refer to the EasySet Bar Code Wand Setup manual
(P/N 1-960560-00) for more information on how to produce
setup bar codes.
The printer will acknowledge that a bar code has been
successfully read by emitting a short beep signal.
If no FNC3 character is found in the bar code, the data will be
stored in a buffer which could be read by specifying the "wand:"
device. The buffer is small, so it is recommended to use short bar
code data (max. 16 characters) and read the buffer regularly to
avoid overflow.
