Abstract:
1. A combined printer-scanner adapted to be moveable by a user relative to a surface and being operable in a scanning mode and a printing mode, the printer-scanner comprising: a speed sensor adapted to measure the speed at which the printer-scanner is moved relative to the surface by the user; a scanning device synchronised with the speed sensor and being adapted, when the printer-scanner is in scanning mode, to capture image data representative of an image disposed on the surface as the printer-scanner is moved relative to the surface by the user; a memory adapted to store the image data; a printhead arrangement synchronised with the speed sensor and being adapted, when the printer-scanner is in printing mode, to effect printing of the image data onto a print media as the printer-scanner is moved relative to the print media by the user, the printhead arrangement comprise a plurality of ink ejection nozzles; a print controller adapted to: a housing adapted to house the speed sensor, the scanning device, the memory, the print controller and the printhead arrangement; a capping arrangement moveable between capped and uncapped positions to thereby selectively cap the printhead, the capping arrangement being movable between a capped position in which the capping arrangement substantially obstructs the ejection of ink from the ink ejection nozzle and an un-capped position in which the capping arrangement dose not substantially obstruct the ejection of ink from the ink ejection nozzles; and a capping actuator disposed on the printer-scanner so as to be operable by a user as the user moves the printhead arrangement relative to the print media; and a contact sensor to sense when the capping arrangement is moved to the un-capped position, wherein the contact sensor transfers a signal to the print controller so that printing occurs when the capping arrangement is sensed to be in the un-capped position.
