Abstract: A printer controller system for controlling printing on media (e.g., a strip of labels) supporting a series of RFID transponders and for communicating detection of void RFID transponders to downstream devices. The printer controller system includes a void detection system for detecting void RFID transponders, a printing system for controlling printing to the media and a void communication system for communicating detection of the void RFID transponder to downstream devices. This allows the downstream device, such as a label peeler, to anticipate the void RFID transponder and deal with it accordingly. The printer controller may include a media advancement system that is configured to continue advancing the media and RFID transponders past the print head even when the RFID transponder is detected and avoid slowing the printing process. The printer controller system may be configured to submit void indicia to a print head and recommunicate a formatted image when a RFID transponder has been voided.

Abstract: A RFID coupler capable of selectively communicating with a targeted transponder from among a group of multiple adjacent transponders. The coupler includes a grounded terminal load, a coupling element, a connecting element, an impedance matching element, and an input terminal. The coupling element is connected with the grounded terminal load and is configured to couple with the transponder by emanating an electromagnetic field. The input terminal is connected to a transceiver for receiving communication signals. The impedance matching element is connected to the input terminal and is configured to substantially match an input impedance of the coupler to a source impedance of the transceiver. The connecting element connects the impedance matching element to the coupling element. The coupling element and the impedance matching element are substantially parallel and separated by at least one dielectric layer and at least one ground plane.

Abstract: A feeder device for feeding a unit of media from a stack of media to a receiving apparatus is provided. The feeder device comprises a drive mechanism for driving the media in a feed direction through an opening defined by a gate apparatus. The opening extends from a first to a second edge of the gate apparatus and defines a fixed height greater than the thickness of the media. A flexible blade member is fixedly engaged with the gate apparatus at a fixed end and is cantilevered with respect to the gate apparatus. The blade member defines a length and extends from the first edge toward the second edge to reduce the opening height. The blade member is further configured to have an adjustable flexibility to allow the feeder device to feed media of varying thickness to the printing apparatus. An associated method is also provided.

Abstract: Various edge detection arrangements are disclosed, including an edge detection method and arrangement that utilizes outputs of commonly illuminated reference and edge sensors as the inputs for a comparator. The reference sensor is configured to have a wide field of view and the edge sensor is configured to have a narrow, high gain, field of view. Therefore, the reference sensor has a broad signal response to an edge passage and the edge sensor a steep and narrow signal response. When the two signals are biased to cross each other, the comparator output changes state, indicating passage of an edge. Because the reference sensor provides a base signal level directly related to the real time illumination level that the edge sensor also receives, the reference sensor provides a switch point along the transition ramp of the edge sensor that integrates a majority of the random error sources.

The print head bracket having alignment forks for aligning the print head with the platen. The printer also includes a platen bracket for maintaining the platen in the printer. The platen bracket being easy to remove to replace the platen.

Abstract: An RFID system for selectively communicating with a targeted transponder from among a group of multiple adjacent transponders is provided. The RFID system may include a transponder conveyance system adapted to transport at least one targeted transponder from a group of multiple adjacent transponders through a transponder encoding area along a feeding direction and an antenna having a resonant inductor and a ferrite material, wherein the ferrite material at least partially covers the resonant inductor and defines an exposed portion of the resonant inductor. In one antenna-transponder alignment, the exposed portion extends substantially parallel to the feeding direction.

Abstract: An XML system (10) configured to print bar code labels, tags, tickets, cards, or other media, and/or encode RFID devices embedded in media, based upon an extensible markup language (XML) input data stream. The XML system includes a computer system (12) operatively coupled to a network (44).

Abstract: An XML processing system for use in a barcode printer apparatus includes a computer system operatively coupled to the barcode printer apparatus. The computer system further includes an XML processor configured to receive, parse, and process an XML input data stream and obtain schema identified in the XML data stream from a schema repository. The XML processor validates the XML data stream based upon the schema obtained. Also included is an XSLT processor configured to obtain a stylesheet identified in the XML data stream from a stylesheet repository. The XSLT processor transforms data in the XML input data stream into transformed XML data based upon the stylesheet obtained. Also, an XSLFO processor formats the transformed XML data into formatted XML data based upon XSLFO instructions contained in the stylesheet. A barcode rendering subsystem then receives the formatted XML data and generates a bit map representative of the bar code label.

Abstract: A thermal printer that includes a thermally conductive sacrificial member disposed between the thermal print head and the web. The sacrificial member is held generally under tension and prevents the web from directly engaging the thermal print head. The sacrificial member may take one of many different forms, including a fixed strip or belt, a rotatable, continuous belt which slowly recirculates during printing to equalize wear across its surface, or a Moebius loop which further provides that wear is equalized across both sides of the belt. By providing a sacrificial member between the print head and web, wear and exposure of the print head is reduced, thereby prolonging the life of the print head.

Abstract: A peel assembly is provided for separating a label from a releasable backing. The peel assembly includes a housing, structure for driving the backing and labels through the housing, a peel bar for bending the backing therearound, a plurality of deflector rollers proximate to the peel bar for deflecting the backing away from the label and towards the peel bar, and a plurality of supporting rollers proximate to the deflector rollers for supporting the label as it exits the peel assembly. After the backing, which has the labels thereon, passes over the peel bar, the backing is passed between the peel bar and the deflector rollers and the label passes over the deflector rollers and then over the supporting rollers.

Abstract: A printer is provided for programming a radio frequency identification (RFID) label and may be used to print indicia on the RFID label.

Abstract: A thermal label printer includes an actuation mechanism and follower for facilitating loading of stock (e.g., label stock). A pivotable printer head pressure plate includes the actuation mechanism which cooperates with the follower coupled to a peeler roller. As the pressure plate is moved from a closed position proximate a platen to an open position for loading of stock or for cleaning the printer head, the peeler roller is automatically translated from the platen. The resulting roller gap and displaced printer head provide unrestricted access for threading of the printer. The printer also includes a programmable device in the printer electronics for reconfiguring the printer to accommodate a variety of thermal print mechanisms.
