A fluid ejecting device with a body defining an array of nozzles. The nozzles are arranged in an array along an array axis. The array has a first portion in which the nozzles are spaced apart along the array axis by a first pitch, and a second portion in which the nozzles are spaced apart by a different second pitch. The array may have a third portion between the first and second portions with a third pitch different from the first and second pitch. An assembly may include two or more of such fluid ejection devices, and the second portion of one print head may be aligned with the first portion of the other print head. Printers incorporating the fluid ejection devices and printing methods are also disclosed.

A backpressure sensor is integrated into a printhead die, or alternatively to a pen body. The backpressure sensor is susceptible to ink pressure from ink within a printhead ink slot, ink channel or nozzle chamber, and to ambient pressure. For the alternative embodiment, the backpressure sensor is susceptible to ink pressure from ink within an ink slot, ink channel or ink cavity away from a printhead die, and to ambient pressure.

A ticket including a base member, a discolorable member carried by the base member, and a discoloration system carried by the base member. The discoloration system is initially configured such that the discoloration system selectively discolors a first predetermined portion of the discolorable member in response to the application of a first energy pulse without discoloring a second predetermined portion of the discolorable member. The discoloration system is also adapted to be reconfigured by the first energy pulse such that the second predetermined portion of the discolorable member will be discolored in response to the application of a second energy pulse.

An inkjet pen includes a multilayered platform, an electrical interconnection extending through the multilayered platform, and a plurality of printhead dies each mounted on the multilayered platform. The multilayered platform includes a first layer having an ink inlet defined therein, a second layer having a plurality of ink feed slots defined therein, and at least one third layer having an ink manifold defined therein. The ink manifold of the at least one third layer fluidically couples the ink inlet of the first layer with the ink feed slots of the second layer. Each of the printhead dies are mounted on the second layer of the multilayered platform and include an array of printing elements and an ink refill slot communicating with the array of printing elements. The ink refill slot of each of the printhead dies communicates with at least one of the ink feed slots of the multilayered platform, and each of the printhead dies are electrically coupled to the electrical interconnection.

A method of printing includes coating a transfer sheet with a first ink component that has an ink thickener; and operating an ink jet printing apparatus to emit a second ink component onto the transfer sheet to form a thickened resulting ink in a selected pattern. The second ink component has a selected dye and a selected solvent in which the thickener is soluble.

A method of mounting a fluid ejection device having a first plurality of pads on a carrier substrate having a corresponding second plurality of pads includes positioning the first plurality of pads with respect to the second plurality of pads, and melting solder between the first plurality of pads and the second plurality of pads. Melting the solder includes aligning the first plurality of pads with respect to the second plurality of pads with a solder reflow force and forming a fluidic boundary between the fluid ejection device and the carrier substrate with the solder.

A printer for creating specialty-sized prints includes a printing mechanism, a cutter mechanism and a slicing mechanism. A media web or sheet is fed into the printer and is advanced by a media advancement mechanism in a media advancement direction. The cutter mechanism cuts the media transverse to the media advancement direction. The slicing mechanism slices the media parallel to the media advancement direction. The slicing mechanism includes a cam positioned on a camshaft and a slicer module. The slicer module is positioned adjacent the camshaft and includes a contact spring operatively spaced from the cam and a blade operatively spaced from the media. The media is sliced when an actuation mechanism rotates the camshaft so the cam pushes against the contact spring of the slicer module, which biases the blade against the media.
