    摘要: A thermal printer includes a capacitor and a power converter operable to step a voltage of a power source, and coupled to charge the capacitor. Printing is controlled based at least in part on a charge state of the capacitor. Delays in charging the capacitor may be avoided where a current line of print data is blank. Operation may be curtailed where the voltage of the power source is below a threshold.

    摘要: The invention concerns a device in printers of the kind wherein an ink ribbon (5) is arranged to be reeled off an unwinding roller (4) and to be wound onto a take-up roller (6) after having passed through a printing unit (7). In order to compensate for any skewing forces occuring in the ribbon (5), the unwinding roller (4) and/or the take-up roller (6) is/are mounted on a rotatable shaft (8) which is provided with a pivot mechanism (9, 11, 12; 21; 22, 24), allowing correcting guide movements of said ribbon (5).
