A presentation output system includes a digital computer network, one or more job submission clients, and a job store. The job store accepts and holds output jobs from the plurality of job submission clients. The presentation output system further includes one or more presentation output devices that pull the output jobs from the job store for outputting.

A producthaving a data encoding patternprinted on it, the pattern defining a grid having a grid spacing, wherein the grid spacing has discontinuities arranged to compensate for a mismatch between the resolution at which the patternis printed and a required value for the grid spacing, the discontinuities being irregularly spaced across the product.

Data encoding pattern

A method and apparatus for producing a document having human-readable content and a position identifying encoding pattern. A printer places text or other content onto a substrate, such as paper, and a filter material application system applies transparent filter material to at least a portion of that content to only modify the reflectivity of the content at a predetermined wavelength. Because the reflectivity of the position identifying encoding pattern remains unchanged, it is distinguishable from the content and can be read at the predetermined wavelength. The position identifying pattern can take a number of forms including a number of dots printed at predetermined positions on the substrate on an imaginary grid.

A method of calibrating a digital pen () comprises the steps of: A digital pen, digital paper and software for calibrating a digital pen and a network comprising a digital pen are also disclosed.

Calibrating digital pens

A digital pen and paper system comprises a pen arranged to make pen strokes on a document having a plurality of regions, to detect markings on the document, and to record them in a series of samples. The system is arranged to determine from the samples the position of the pen strokes. The system has defined therein a plurality of different warning conditions that determine when a warning will be produced in response to lost samples, and is arranged to select one of the warning conditions for one of the pen strokes depending on which of the regions the pen stroke is made.

Digital pen and paper

A communication system includes a computer network that includes a plurality of interconnected computer devices. The communication system further includes at least one network device capable of communicating with one or more mobile wireless devices. The network device is part of the computer network and is capable of communicating with a mobile wireless device without the mobile wireless device being a member of the computer network.

Use of very small advances of printing medium for improved image quality in incremental printing

In a method for operating an ink jet printer with a curved platen the firing of the ink nozzles of the print heal is controlled in a specific way to avoid the effects of misplacement of ink dots on the printing medium due to the curvature of the platen and other effects. The printing of markings on the printing medium is performed in several passes of the print head whereby the medium is advanced between passes. During a pass, central nozzles are fired more often than nozzles at the periphery of the print head because the precision for peripheral nozzles is worse than for central nozzles. Printing during a single pass is thus performed in bands whereby the amount of ink placed in central bands is higher than in peripheral bands.
