The present invention is a set-top box integrated with a low-height printer. The printer includes an input tray for storing input media sheets and an output area for holding output media sheets. The printer further includes a printhead that scans and prints on the media sheets from the front to the back of the printer. The media sheets are stored in the input tray in a landscape orientation and are held in the output area in a semi-curled position. Alternatively, the media sheets are stored in the input tray in a portrait orientation.

A displaceable print cartridge chute for an inkjet printer. The chute holding the print cartridges is displaceable from the carriage that sweeps the cartridges relative to the media during printing. The chute can be moved from a printing position engaged with the carriage to a service position adjacent a side of the printer so as to facilitate installation and removal of the cartridges through the side rather than the top of the printer. Because cartridges are serviced through the side, a printer incorporating the displaceable print cartridge chute can be stacked with other electronic equipment.

An inkjet printer and method of printing to reduce printer footprint size using printhead service stations comprised of printhead wipers, priming and capping apparatus at each end of the path of travel of a printhead carriage having multiple printheads. Selected printheads are serviced in each service station and selected printheads may be used for printing in opposite directions to further reduce footprint size of the printer.

Discrete pen wiping and pen specific print direction to reduce size of

Large, overlapping 'mega-dots', placed on small, high resolution pixel locations, are used in high quality monochrome imaging to preserve information to the micro, or pixel, level, thus avoiding the need to use micro-sized droplets. By using multiple passes and multiple pens with different levels of gray ink, one may build a single monochrome 600 dpi (dots per inch) pixel with the composite gray of those droplets at that pixel location as well as the neighboring locations. With careful print modes and multiple passes, one can produce several levels of gray at a particular pixel location. The biggest advantage of using multipixel dots is that the sensitivity to trajectory errors is significantly reduced. For example, a dot that is 1/150.sup.th inch diameter is almost indifferent to a 1/1200.sup.th trajectory error. Even a relatively large 1/600.sup.th inch error has little impact on the large 1/150.sup.th dot (25% error). In reducing the sensitivity to trajectory errors, overall imaging errors, such as banding, can be reduced, and overall image quality enhanced. Optimally, the large dots have a diameter that is about three to five times the pixel size, providing an overlap of three to five dots, respectively.
