    摘要： A printing system includes a printing device, a platen roller, a controller, and an interface. The printing device includes a thermal head, a ribbon drive source, and a head drive source. When receiving a print command, the controller executes head movement control for moving the thermal head and ribbon acceleration control for accelerating a transport speed of an ink ribbon to a target speed. After completion of the head movement control and the ribbon acceleration control, the controller is configured to control the thermal head to perform printing on the print medium. At least before receiving the print command, the controller is configured to determine a printable distance over which the print medium is transported from the reception of the print command till the completion of the head movement control and the ribbon acceleration control and outputs the determined printable distance through the interface.

    摘要： The printing machine (1) comprises: a supporting structure (11); a thermal transfer assembly (20) movable in a predetermined horizontal direction (21) and comprising a rotatable motorized transfer roller (30) and heating means (70, 71) associated to the transfer roller (30), wherein the transfer roller (30) and the associated heating means (70, 71) are movable vertically towards and away from a path of the articles (A) to be printed; and supply means (2; 12-16, 33-40) arranged to advance a printing ribbon (N) which on a side facing the articles (A) carries at predetermined intervals images formed of a thermally transferable ink. The thermal transfer assembly (20) further comprises first and second deviation rollers (35, 36) whose axes of rotation are horizontal and substantially parallel to one another and to the axis of rotation (x) of the transfer roller (30). The deviation rollers (35, 36) are arranged one upstream and the other downstream of the transfer roller (30) on the path of the printing ribbon (N) and are displaceable vertically towards and away from said path of the articles (A). The printing machine (1) further comprises first and second motor means (43, 44) associated each with a respective deviation roller (35, 36), said first and second motor means (43, 44) being controllable independently of one another, whereby each of the deviation rollers (35, 36) is selectively displaceable vertically independently of the other one.
