    摘要： According to one embodiment, a printer includes a conveying mechanism, a first image forming unit and a coloring conversion mechanism. The conveying mechanism conveys a medium. The first image forming unit forms an image on the medium with a temperature-sensitive ink whose color changes depending on temperature. The coloring conversion mechanism converts a coloring state of the image with the temperature-sensitive ink by heating or cooling the image with the temperature-sensitive ink.

    摘要： If it is determined that a portable storage medium is held in a medium access unit (Yes in ACT S2) and it is determined that information to change at least one of a various setting data file storing various kinds of setting information that are necessary for printing and a program to control printing is stored in the portable storage medium (Yes in ACT S3), the information to change at least one of the setting data file and the program is loaded to a setting data storage unit (ACT S4). Thus, if the program and the setting data file are set and copied to a predetermined area in the portable storage medium, the program and the various setting data file can be automatically set by inserting and starting up the portable storage medium in the medium access unit of another printer. Therefore, many printers can be easily upgraded.

    摘要： A liquid discharge recording head in which a nozzle plate is formed from inorganic material can be manufactured at low cost and with good through-put. In the liquid discharge recording head, a nozzle plate formed from inorganic material is stacked on a front surface of a silicon substrate including heat generating resistor members for generating energy for discharging liquid and an electric circuit for driving the heat generating resistor members. The liquid can be supplied from a liquid supply port extending through the silicon substrate to flow paths provided between the silicon substrate and the nozzle plate. Recessed portions having predetermined depths are formed in regions of the surface of the silicon substrate, where the flow paths are formed, and discharge ports are formed above the recessed portions.

    摘要： In a method for producing an ink-jet recording head, a plurality of through-holes is formed in a heat storage layer formed on one surface of a silicon substrate, subsequently, heating elements are formed, and a protective layer is formed on the substrate. A passage-forming member forming discharge ports and ink passages is formed on the protective layer and an ink supply port is then formed by anisotropic etching from the other surface of the silicon substrate. In this step, since the protective layer serves as an etching stop layer, the passage-forming member is not in contact with an etchant. Subsequently, the protective layer formed in the through-holes is removed so that the ink supply port includes a filter.
