PORTABLE DEVICE AND METHOD FOR PRINTING AN IMAGE, RECORDING MEDIUM, PEN AND BENCHMARK FOR SAID DEVICE

摘要

The invention relates to a portable device for printing an image in a printing area provided on a material substrate, which includes: at least one removable benchmark (96-99) capable of being manually positioned on the substrate and associated with a corresponding point of the image being printed by means of a predefined relationship separate from the position of said benchmark on the substrate, a measurement unit capable of measuring the position of the printing head relative to the benchmark, and a control unit (14) capable of determining the distance separating the pen from the substrate, from the measurement of the position of the printing head, and of preventing the image from being printed on the substrate if said distance is greater than a predetermined threshold.
