A method of communicating non-native print objects in MO:DCA Architecture
for controlling and operating RFID writer or reader devices without
requiring separate control data streams or systems to be implemented at
the host computer. Data references and command identifiers are placed by
application program means at the host computer into the page description
data so that RFID information can be retrieved and downloaded to the
printer and RFID apparatus when the print data is being processed in the
print server or main processor of the printer without interfering with
normal operation of the printer itself.
