A print head assembly for a media processing device comprises: a print head including an interface and a latch receiver on an upper surface of the print head; and a print head carrier including: (i) a base plate having an opening to receive the latch receiver therethrough when the print head is positioned at a lower surface of the base plate; (ii) an adapter to engage with the interface of the print head; and (iii) a latch bar on an upper surface of the base plate, the latch bar slideable between a first position to engage with the latch receiver and lock the print head to the base plate, and a second position to disengage from the latch receiver and release the print head from the base plate.

Print head mechanism

A media processing device is disclosed. An example media processing device includes memory including machine-readable instructions; and a processor to execute the machine-readable instructions to control a printhead assembly, the processor being configured to communicate with the printhead assembly in accordance with a pin configuration, wherein the pin configuration includes pin groups, and each of the pin groups includes a signal line and a reference voltage, wherein the signal line pin is coupled to a source of changing values, and the reference voltage pin is coupled to a constant voltage.

Printhead pin configurations

Printhead pin configurations are disclosed. An example printhead assembly includes an interface to place the printhead assembly in communication with a logic circuit; and a logic circuit configured according to a pin configuration, the pin configuration comprising pin groups, wherein each of the pin groups includes a signal line and a reference voltage.

A Main Logic Board having an electrically configurable option board interface (ECOBI) to facilitate connection of option boards into apparatus for providing optional functions. Once connected to the host, an Option board provides identification (ID) data to the main logic board host processor. The host processor determines the interface configuration necessary to enable communication between the host and the option board based on the option board ID, then configures electrically configurable interface circuitry for operational compatibility. The option board may provide an interface driver directly to the host for configuration of the interface. The interface may comprise a standard interface protocol such as PCI or USB that the host configures through the same connection to the option board.

Electrically configurable option board interface

Systems, methods, and apparatuses are disclosed for providing a high speed adaptive thermal printhead interface. In one embodiment, an apparatus is provided comprising at least one processor; and at least one memory including computer program instructions, the computer program instructions being configured to, when executed by the at least one processor, cause the apparatus at least to determine identifier information for a connected printhead; retrieve printhead interface configuration data for a configurable printhead interface based at least in part on the identifier information; configure printhead interface circuitry in accordance with the printhead interface configuration data; and enable communication with the printhead through the configurable printhead interface.
