This invention concerns inks for use in ink-jet printers for printing on to impervious or non-porous substrates such as, for example, glass, ceramics, plastics such as, for example, polycarbonate, polyvinyl chloride, cellulose acetate butyrate, and metals. The linear drive includes a piston seated movably in a cylinder and loadable with a pressure-bearing medium on one or both ends and the tubular holder is fixed in the piston. For each mobile device, the wireless context of the mobile device includes a wireless Personal Area Network context of the mobile device, a wireless Local Area Network context of the mobile device, or both. Additionally the present invention provides a novel means of using context information to create multimedia file presentations; image or video file presentations that can be associated with previous periods of time, locations or other context data. As the handset changes location, it determines its new location and compares it to the coordinates provided by the server. The reading section and the stencil making section are juxtaposed on the single conveyance section, and the conveyance of the original to the reading section and the conveyance of the stencil sheet to the stencil making section are performed by the single conveyance section.
