Chapter 7 User Fault Generation
User Fault Generation
User fault generation is a feature that allows 3rd party applications to stop the
printing operation and display a sixteen character message on the printer’s
operator panel.
Using this feature in conjunction with the telemetry data export function allows
external programs to implement a closed-loop telemetry data solution. If the
external program detects an error, it can terminate all further printing to
reduce bad labels and label stock waste.
The AutoID Data Manager provides this feature through the XML remote
control interface. If a properly formatted XML message is sent to the AutoID
Data Manager XML port, it will cause the AutoID Data Manager to issue a
printer fault command to the specified printer. The fault command will cause
the printer to go offline and display a 16 character text message on the
printer’s operator panel.
The following is the proper XML message format needed to generate a user
fault:
^B
^F
where:
myprinter is the name of the printer specified in the printer database
some message is the text message to be displayed on the printer’s operator
panel.
NOTE: The maximum length of the text message is 16 characters. Messages
longer than 16 characters will be truncated.
