A high speed tabletop and industrial printer is disclosed with integrated high speed RFID encoding and verification at the same time. The industrial printer simultaneously prints on and electronically encodes/verifies RFID labels, tags, and/or stickers attached to a continuous web. The industrial printer comprises a lighted sensor array for indexing the printing to the RFID tags; and a cutter powered from the industrial printer for cutting the web that the RFID tags are disposed on. The industrial printer comprises two RFID reader/writers that are individually controlled. Specifically, one of the RFID reader/writers comprises the ability to electronically encode the RFID tags while the web is moving; and the second RFID reader/writer uses an additional RFID module and antenna on the printer for verifying the data encoded to the RFID tags.

The compact thermal printing mechanism according to the invention is applicable for handheld payment terminals. The invention provides a printer chassis (1) with reinforced flat area (20) by at least one reinforcing element comprising a fold of the printer chassis (1). This folded portion of the printer chassis strengthens the chassis and provides a very strong resistance to bending forces of the lateral pressure means (18) of the platen roller (6). The stable and uniform pressure distribution across the paper width ensures uniform print quality.

A formative surface having a conductive base covered with a dielectric and oleophobic/hydrophobic surface layer is created with defined pits to grow micro-puddles of a defined volume. The formative surface is brought into close proximity with a charge retentive surface carrying a charge image. Fountain solution vapor nucleates and grows preferentially on the base of the pits as micro-puddle droplets. The puddles are charged and extracted from the surface to provide a fog of charged droplets of narrow volume and charge distribution. The charged droplets are attracted and repelled respectively from the charged and discharged image regions of the charge retentive surface, thus developing the charged image into a fountain solution latent image. The developed latent image is then brought into contact with a transfer member blanket and split, thus creating on the blanket a fountain solution latent image ready for inking.

Ink-based digital printing systems useful for ink printing include a secondary roller having a rotatable reimageable surface layer configured to receive fountain solution. The fountain solution layer is patterned on the secondary roller and then partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate. To achieve a very high-resolution (e.g., 1200-dpi, over 900-dpi) print with these secondary roller configurations, an equivalent very high-resolution fountain solution image needs to be transferred from the secondary roller onto the imaging blanket. To increase the resolution of the image on the secondary roller, examples include a textured surface layer added to the secondary roller for contact angle pinning the fountain solution on the roll. Approaches to introduce a micro-structure onto the surface layer of the secondary roller, and also superoleophobic surface coatings are described.

Based on evaporation of fountain solution from a rotating blanket cylinder to create an image that may be inked and printed, a digitally addressable heater array at or just below the blanket surface evaporates deposited fountain solution and forms a fountain solution latent image on the surface. The heater array has controllable heating elements (e.g., field effect transistors, thin film transistors) that provide a transient heat pattern on the surface to evaporate the fountain solution. Heat is generated by current flow in the heating elements, and power developed by the heating circuit is the product of source-drain voltage and current in the channel. Current may be supplied along data lines by an external voltage controlled by digital electronics to provide the desired heat at heating elements addressed by a specific gate line. The heater array may include a current return line that may be a 2-dimensional mesh.

A thermal head includes a substrate, a plurality of heat generating portions, electrodes, pads, driving ICs, and a wire. The plurality of heat generating portions are positioned on the substrate and arranged in a main scanning direction. The electrodes are positioned on the substrate and electrically coupled to each of the plurality of heat generating portions. The pads are positioned on the substrate and coupled to the electrodes. The driving ICs drive the heat generating portions. The wire couples the driving ICs and the electrodes to each other. The thermal head according to the present disclosure includes a plurality of the pads. At least one of the pads is a multi pad that has a first region to which the wire is connected and a second region to which each of a plurality of probes is connected.

A thermal print head includes a heat-generating substrate, a resistor layer, a conductive layer, a first substrate, a second substrate, and a third substrate. The heat-generating substrate includes a heat-generating substrate obverse face and a heat-generating substrate reverse face that are spaced apart from each other in a thickness direction. The resistor layer is supported by the heat-generating substrate. The conductive layer is supported by the heat-generating substrate, and electrically connected to the resistor layer. The first substrate is located upstream of the heat-generating substrate in a sub-scanning direction. The second substrate is located upstream of the first substrate in the sub-scanning direction. The third substrate is bonded to the first substrate and the second substrate and higher in flexibility than the first substrate.
