摘要:
It is necessary that paper be moved past the printhead at a constant velocity to obtain artifact-free printing. Therefore the printhead requires a constant stream of data during printing. Whilst it is possible to rasterize the page using a page description language directly to the printhead, it is uneconomical. Hence the redering is carried out in the PC. However, the standard USB peripheral connection is the standard connection on PCs, which places a constraint on the limit of data per page that can be transmitted to the printer and still obtain a reasonable rate of printing. Thus the contone images and graphics are rendered in the PC to a pixel level, and the black text and graphics are rendered in the PC to a dot level, where the rendered data is compressed and transmitted to the printer. The transmitted data is decompressed and combined and the images overlaid and printed.

Machine-readable coded data disposed on or in a substrate. The coded data includes a plurality of layouts, each of which has order n rotational symmetry. The layout encodes a first codeword formed from a sequence of n first symbols distributed at n locations about the center of rotational symmetry of the layout. In use, decoding the first symbols at each of the n orientations of the layout produces n representations of the first codeword, with each representation being a different cyclic shift of the first codeword so as to indicate the degree of rotation of the layout. The layout also encodes a second codeword formed from a number of second symbols, the second codeword being indicative of information regarding the respective layout.

A method of printing a copy of a document, using an original printed document having a zone including coded data, the method including the following steps: (a) receiving a request from an optical sensing device, the request being generated in response to a user directing the optical sensing device towards the zone on the original document, which causes the optical sensing device to sense coded data on the original document and transmit a message to the printer indicative of a copy request, or to the computer system operatively connected to the printer; (b) retrieving a copy of the original document from a memory of the computer system in response to receiving the request; and (c) printing the retrieved copy.
摘要:
The present invention provides a method of minimizing absorption of visible light in an ink composition comprising an IR-absorbing metal-dithiolene dye, comprising preselecting said dye such that it includes at least one moiety for reducing intermolecular interactions between adjacent dye molecules. The method is especially suitable for use in connection with netpage and Hyperlabel systems.
