摘要:
There is described a thermal printer assembly (10) which includes an elongated thermal print head (12) oriented substantially orthogonally to a print media path (17) and a platen roller (16), aligned with and opposed to the elongated thermal print head (10), and adapted to pressure the print media (16) against the print head (10). The assembly may include one or more additional print heads (12, 24).
摘要:
There is described a roller assembly which may be utilized in a linear or serial printer. The roller assembly includes a platen roller including a central axle being exposed at opposing ends of the roller and a frame for mounting the platen at both exposed axle ends.
摘要:
A thermal printer is disclosed which includes a plurality of thermal print heads, each of the plurality of thermal print heads being operable to print a distinct one of a plurality of colors. The plurality of thermal print heads may print output at a plurality of spatial resolutions. The thermal printer may include dot size varying perceived levels of color printed by the thermal printer by varying sizes of dots printed by the plurality of thermal print heads. The printer may perform various image processing steps on an image to be printed, such as tone scale adjustment, thermal history control, and common mode voltage correction, to improve the perceived quality of the printed image. The thermal printer may be incorporated into a digital photo-printing vending machine for printing images provided by a customer.
摘要:
There are described metal-complexed azo dyes which are useful in ink jet printing applications. Also described are ink jet ink compositions including a dye of the invention as well as ink jet printing methods and apparatus.

Techniques are disclosed for using the display rendering engine of a web browser to render content in a form suitable for output by a printer. The content is described by a content description, which may describe the content using any appropriate language, such as the Hypertext Markup language (HTML). An output device description describes the printer according to input parameters of the web browser display rendering engine. The content description and the output device description are provided as inputs to the web browser display rendering engine, which generates the rendered content. The rendered content, once generated, may be captured, stored, and transmitted to the printer, which may print the rendered content. Some or all of the steps just described may be performed without displaying the rendered content on a display monitor. The web browser display rendering engine may be the display rendering engine of a conventional web browser.
摘要:
An improved camera and method of processing an associated film assemblage of the self-developing type, wherein the assemblage is provided with a plurality of self-developing film frames. Each frame carries an integral self-developing unit as well as an associated processing fluid pod. Each exposed frame is manually pulled through pressure applying members for rupturing the pod and spreading the fluid before exiting. Simultaneously, the next successive film unit is pulled from a container therefore and indexed by means on the assemblage to the film plane as the pulled unit is automatically separated from the remainder of the assemblage.
