  • Patent number: 11225087
    Abstract: A method of controlling a hand-operated printer (3) includes detecting a transverse movement of the hand-operated printer (3) after finishing a first swath (1). The method compares a transverse distance covered by the transverse movement with a predetermined transverse distance (11) between said first swath (1) and a second swath (2). A transverse-stop signal is emitted when the transverse distance covered by the transverse movement reaches the predetermined transverse distance (11).
