Method and apparatus for controlling radio frequency identification device apparatus in a printer
The print system MO:DCA Architecture is extended to handle non-native print objects for controlling and operating RFID writer or reader devices without requiring separate control data streams or systems to be implemented at the host computer. References and command identifiers are placed in the page description data from the host computer 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.
1 . Apparatus comprising:
a printer;
an RFID device operatively associated with said printer and functioning to read or write RFID tags; and
a controller which provides to said printer and said RFID device digital data and control signals in an architected data stream which comprises both printer control data and RFID device control data; and
a branching circuit element which distinguishes between RFID control and data signals and printer control and data signals and delivers the distinguished control and data signals to said printer and said RFID device, respectively.
2 . Apparatus as described in claim 1 , wherein:
said architected data stream is a Intelligent Printer Data Stream (IPDS) comprising at least a page of data objects for inclusion on a base medium and wherein said branching circuit comprises an object processor for rendering each object in said architected data stream for presentation to either said printer or said RFID device in accordance with said distinguished control signals.
3 . Apparatus as described in claim 1 , wherein:
said architected data stream is a formatted data stream comprising presentation parameters for RFID data objects.
4 . Apparatus as described in claim 2 , wherein:
Said architected data stream is a formatted data stream comprising presentation parameters for RFID data objects.
5 . Apparatus as described in claim 1 , wherein:
said architected data stream is an IPDS structured data stream comprising page-level presentation data objects for inclusion directly on a rendered page.
6 . Apparatus as described in claim 1 , wherein:
Said architected data steam is an IPDS structured data stream comprising reference instruction parameters for specifying delivery of control and data objects to said RFID device from prestored data objects present at said apparatus.
7 . Apparatus as described in claim 2 , wherein:
Said architected data steam is an IPDS structured data stream comprising reference instruction parameters for specifying delivery of control and data objects to said RFID device from prestored data objects present at said apparatus.
8 . Apparatus as described in claim 3 , wherein:
Said architected data steam is an IPDS structured data stream comprising reference instruction parameters for specifying delivery of control and data objects to said RFID device from prestored data objects present at said apparatus.
9 . Apparatus as described in claim 4 , wherein:
Said architected data steam is an IPDS structured data stream comprising reference instruction parameters for specifying delivery of control and data objects to said RFID device from prestored data objects present at said apparatus.
10 . Apparatus as described in claim 5 , wherein:
Said architected data steam is an IPDS structured data stream comprising reference instruction parameters for specifying delivery of control and data objects to said RFID device from prestored data objects present at said apparatus.
11 . Apparatus as described in any one of claims 1 through 10 , wherein:
Said architected data stream comprises at least one RFID data and control data object in an Include Object (IOB) structured data field and said branching circuit element ignores unneeded parameters specified for said RFID device in said data stream.
12 . Apparatus as described in any one of claims 1 through 10 , wherein:
Said data stream is structured in an MO:DCA protocol format including all of the control parameters for each data object of any kind in said data stream.
13 . Apparatus as described in claim 6 or claim 7 , wherein:
Said RFID data and control objects are included directly into an MO:DCA protocol formatted object container and specified within an MO:DCA page.
14 . A method for printing and memory tag writing or reading from or to a base printing medium comprising steps of:
providing a printer and an RFID device with digital data and control signals in an architected data stream which comprises both printer control and RFID device control; and
distinguishing RFID device control and data signals from printer control and data signals; and
delivering said identified control and data signals to the printer and RFID device, respectively.
15 . A method as described in claim 14 , further comprising steps of::
including in said architected data stream at least a page of data objects for inclusion on a base medium and
identifying each object in said architected data stream for presentation to either the printer or the RFID device in accordance with each said identified object.
16 . A method as described in claim 14 , further comprising steps of:
formatting said data stream with IPDS presentation parameters for said RFID data objects.
17 . A method as described in claim 15 , further comprising steps of:
formatting said data stream with IPDS presentation parameters for said RFID data objects, and
including reference parameters specifying delivery of control and data objects from prestored objects present at said printer and RFID device.
18 . A method as described in any one of claims 14 through 17 , further comprising steps of:
delivering separated control and data objects to the printer and to the RFID device and;
ignoring unneeded parameters specified in said data stream when specified for an RFID data object.
19 . A method as described in any one of claims 14 through 17 , further comprising steps of:
structuring said architected data stream in the MO:DCA protocol format and including all of the control parameters for each data object in said stream.
20 . A method as described in any one of claims 14 through 17 , further comprising steps of:
including said RFID data objects directly into an MO:DCA protocol formatted object container.
