A radio frequency identification (RFID) printer device for electronically encoding and verifying RFID labels, the RFID printer device comprising a thermal printhead, a platen roller, a first RFID antenna configured upstream from the thermal printhead and the platen roller, a second RFID antenna configured downstream from the first RFID antenna, a memory device having executable instructions stored therein, and one or more processors communicatively coupled to the memory, the one or more processors, in response to the executable instructions, configured to transmit data via the first RFID antenna, wherein the data is encoded to one or more RFID tags associated with respective one or more RFID labels during a first RFID communication window, and receive and transmit data via the second RFID antenna to verify the encoded data during a second RFID communication window.

Multi-antenna RFID printer

A verifier and printer assembly are provided. The verifier and printer assembly include a verifier module and a printer. The verifier has a magnetic docking element and the printer includes a docking portion operable to dock the verifier module. The magnetic docking element and the docking portion interact with each other to removably couple the verifier module to the printer. A magnetic attachment system for the verifier module and methods for removably coupling the verifier module and the printer for verification of a printed machine-readable symbol are also provided.

Removably couplable printer and verifier assembly

Example safety mechanisms for example printing apparatuses are provided. An example printing apparatus may include at least one linear guide disposed on a first surface of a back-spine section of a printer body and a top chassis portion coupled to the at least one linear guide. In some examples, the top chassis portion may include a laser safety casing. In some examples, the laser safety casing may comprise a laser module configured to emit a laser beam along a laser path and a safety cover that is moveable to a first cover position intersecting the laser path.

Safety mechanism for printing apparatus

A width detecting system includes a sensor-LED array positioned across a path of a media and/or ribbon within a printing apparatus. The LEDs are adapted to produce light directed toward the media and/or ribbon path. The optical sensors are configured to detect the LED light, produce analog signals proportionate to the received amount of light, and transmit the signals to a signal receiving assembly for processing. Additionally or alternatively, a width detecting system can have an array of LEDs facing an array of sensors in such a way that the media and/or ribbon path is located between the arrays. A method for width detection includes analyzing sensor data to determine one or more transition point between media and no-media sections, and calculating media width. The method can include using sensor data collected for a reflective and/or transmissive sensor arrays, and can be used for media and/or ribbon width detection.

Automatic width detection

Systems and method for estimating a remaining amount of a consumable resource are provided. According to one method, a first step of detecting the center of mass of a mobile printer is conducted, wherein the mobile printer comprises print media. The method may also include a step of determining a remaining print media level based on the detected center of mass.

Estimating a remaining amount of a consumable resource based on a center of mass calculation

A printer is provided which includes a control unit and a print head with a burn line and a platen roller. The print head is coupled to the control unit. The print head is positioned in a vertical orientation relative to the platen roller over which a media label passes during printing. A radio frequency identification (RFID) reader, coupled to the control unit, for programming RFID tags on the media label is also provided. The RFID reader is coupled to a RFID antenna. The RFID antenna is above the media label path, the print head's vertical orientation allowing the RFID antenna to be accommodated in close proximity to the print head burn line. Further, a label stop sensor (LSS) module is provided, coupled to the control unit, for monitoring movement of the media label along a media path. The LSS module is disposed adjacent to the RFID antenna.

Printer, system and method for programming RFID tags on media labels

The present invention embraces a method and apparatus for providing feedback to a user on the status of media or ribbon of a printer. The feedback may be provided by incorporating a feedback mechanism in a hanger of a printer. The printer may be a thermal printer, but may be another type of printer. The feedback mechanism of the printer may be designed to work with one or more sensors to provide a feedback loop so that without an input from a user, the printer is able to detect the presence/absence of media or ribbon, as well as determine the width of the loaded media or ribbon. In another embodiment, the feedback mechanism is able to determine the weight of the roll of media or ribbon and hence determine the quantity of media or ribbon available on the hanger.

Smart media hanger with media width detection

A printer is configured with a processor which calculates printhead control parameters, the control parameters being determined by the processor in such a way as to optimize the printing process of the printer's printhead. The processor determines the printhead control parameters according to an optimization algorithm stored in the printer. To maintain the internal security of the optimization algorithm, the printhead control parameters are encrypted by the processor. The encrypted printhead control parameters are then transmitted to the printhead via an internal data path of the printer. If a third party monitors the data along the internal data path, the encryption algorithm remains secure because the control parameters are encrypted. The printhead contains a second, dedicated processor. The printhead processor receives the encrypted printhead control parameters, and decrypts the control parameters. The printhead then prints according to the decrypted printhead control parameters, ensuring optimized printing.

Cryptographic printhead

Methods and apparatus to detect if an authorized thermal print head (TPH) has been installed in a specific model or manufacturer printer are provided. The method provides a system to check the resistivity or impedance value at the TPH side, either upon printer boot-up or during printing operation. During printing operation, the impedance measurement may be executed for a time period at a fixed periodicity and/or one or more events. Based on the impedance measurement, the printer may determine that the impedance value matches the authorized TPH range value. In a case of non-matching impedance values or change of impedance values, the printer may prevent printing operation until an authorized TPH is installed.

Secure thermal print head

The present disclosure relates to devices, systems, and methods providing a ribbon sensor configured and positioned to ascertain an orientation of a printing ribbon, including devices, systems, and methods configured for detecting an improperly oriented printing ribbon, and for triggering a response in the event of an improperly installed, and/or for confirming proper installation of a printing ribbon.

Detecting printing ribbon orientation

A printer comprises a processor; a media hanger comprising a sensor array receiving space extending along a length of the media hanger; and a sensor array positioned in the sensor array receiving space and communicatively connected to the processor, the sensory array comprising a plurality of sensor pairs, each sensor pair having an emitter and a receiver, the sensor array being configured to: emit light from the emitter outward from the media hanger, detect the emitted light after the emitted light is reflected off a surface of media loaded on the media hanger, transmit signal intensity of the reflected light detected by each of the sensor pairs to the processor; wherein the processor is configured to determine a width of the media loaded on the media hanger based on the signal intensity detected by each of the sensor pairs.
