1. A mobile telecommunications device comprising a casing, a display, circuitry for wireless telecommunications housed within the casing and a printer housed within the casing, the printer comprising:

  • a printhead arrangement adapted to effect printing onto print media as the printer is moved relative to the print media, the printhead arrangement including a plurality of ink ejection nozzles;

    an ink supply adapted to store ink and to supply the ink to the printhead arrangement;

    a speed sensor adapted to measure the speed at which the printhead arrangement is moved relative to the print media and to generate speed data; and

    a print controller adapted to;

    (a) receive image data from an image source;

    (b) convert the image data into a plurality of drop ejection control signals;

    (c) receive the speed data from the speed sensor; and

    (d) operate the ink injection nozzles in the printhead arrangement in accordance with the drop ejection control signals at a rate determined using the speed data, to thereby effect printing of the image data onto the print media wherein the speed sensor comprises;

    an optical encoder wheel adapted to be in contact with the print media and to rotate as the device is moved relative to the print media, the optical encoder wheel having a series of circumferentially spaced markings thereon; and

    an optical sensor adapted to;

    (a) detect the markings as the markings pass the optical sensor during rotation of the optical encoder wheel; and

    (b) generate the speed date from the detected markings;

    the mobile telecommunications device further comprising a capping arrangement moveable between a capped position in which the capping arrangement substantially obstructs the ejection of ink from the ink ejection nozzles and a un-capped position in which the capping arrangement does not substantially obstruct the ejection of ink from the ink ejection nozzles, the capping arrangement being actuated by a capping actuator disposed on the device so as to be operable by a user as the user moves the printhead arrangement relative to the print media.
