    • A thermal printer for printing on a continuous print medium by ink transfer from a thermal print ribbon has a print head (22) which is pivotally mounted and which is driven in an oscillatory nodding motion by means of a stepper motor (14) so as repeatedly to bring a linear array of energisable printing elements to bear against a platen roller (44). Both the element array and the platen (44) extend transversely to respective paths of travel of the print medium (50) and the ribbon (42). The print medium is fed through the printer from an inlet region (53), between the platen and print head, and thence to an outlet region (54). The instantaneous rate of travel of the print medium past the print head is substantially the same as the rate of feed of print medium to the printer. Typically this rate is of the order of 250 to 400 mm per second. The ribbon (42) also travels between the print head and the platen, overlying the print medium and is driven in such a manner that it travels at the same rate as the print medium during each printing operation. Between each printing operation the ribbon (42) is driven in reverse to rewind any unused portion of ribbon which has overshot the printhead (22).
    • 一种用于通过从热敏打印带传送油墨在连续打印介质上打印的热敏打印机具有可旋转地安装的打印头（22），并且通过步进电机（14）以反复方式以振荡点动运动驱动 以使可激励的打印元件的线性阵列抵靠在压纸辊（44）上。 元件阵列和压板（44）横向延伸到打印介质（50）和色带（42）的相应行进路径。 打印介质从入口区域（53），压盘和打印头之间，然后到出口区域（54）通过打印机进料。 打印介质经过打印头的瞬时行进速率与打印介质向打印机的进给速率基本相同。 通常这个速率是每秒250到400毫米的数量级。 色带（42）还在印刷头和压板之间移动，覆盖在打印介质上并且以这样的方式被驱动，使得它在每次打印操作期间以与打印介质相同的速率行进。 在每次打印操作之间，色带（42）被反向驱动以重新卷绕打印头（22）的任何未使用的色带的部分。

    • A color thermal printer (10) loads a dye receiver (30) for printing by moving the dye receiver (30) in a first direction through a gap between a print head (23) and a platen (24). A dye donor (20), also positioned in the gap, moves in the first direction during receiver loading. The moving dye donor (20) engages the dye receiver (30), assisting the dye receiver (30) through the gap. When the dye receiver (30) is detected downstream of the gap, the dye receiver (30) is positioned in a beginning receiver print position and the position of the dye donor (20) with respect to the print head (23) is determined. If the print head (23) position is downstream of a beginning donor print position, the dye donor (20) is rewound in a second direction opposite the first direction until the print head (23) is upstream of the beginning donor print position, whereupon the dye donor (20) is moved to the beginning donor print position. If the print head (23) position is upstream of the beginning donor print position when the dye receiver (30) is detected, the dye donor (20) is moved to the beginning donor print position. A normal printing sequence occurs when both dye donor (20) and dye receiver (30) are in their respective beginning print positions.
    • 彩色热敏打印机通过沿着第一方向移动染料接收器通过打印头和压板之间的间隙来装载用于打印的染料接收器。 也位于间隙中的染料供体在接收器加载期间沿第一方向移动。 移动的染料供体与染料接收器接合，通过间隙辅助染料接收器。 当在间隙的下游检测到染料接收器时，染料接收器定位在开始的接收器打印位置，并确定染料供体相对于打印头的位置。 如果打印头位置在开始的供体打印位置的下游，则染料供体在与第一方向相反的第二方向上重绕，直到打印头位于起始供体打印位置的上游，于是染料供体移动到起始供体 打印位置。 如果当检测到染料接收器时打印头位置在开始施主打印位置的上游，则染料供体移动到开始的供体打印位置。 当染料供体和染料接收器处于它们各自的开始印刷位置时，发生正常的印刷顺序。
