    • In a method and apparatus for improving the printing with a thermotransfer print head, an energy value is calculated before the printing process according to different types to be implemented when a dot is to be printed. Energy values also are calculated for the heating elements at the ends of the row of heating elements of the high-resolution thermotransfer print head, so as to activate these heating elements even though in heating phases no dot to be printed at the border external to the barcode image. Additionally, those heating elements that do not lie in the two border regions of the heating element row are also activated for a limited time duration, the aforementioned time duration directly preceding the printing of a barcode image. A microprocessor calculates the energy values and is connected with a pixel energy memory for non-volatile buffering of the data that are transferred into a print data controller and are converted into a print pulse duration.
    • 在利用热转印打印头改善打印的方法和装置中,在打印点之前根据要实现的不同类型在打印处理之前计算能量值。 对于高分辨率热转印打印头的加热元件行的端部处的加热元件也计算能量值,以便激活这些加热元件,即使在加热阶段中,在加热阶段没有点印刷在外部的边界 条形码图像。 此外,不在加热元件列的两个边界区域中的那些加热元件也在有限的持续时间内被激活,上述持续时间直接在条形码图像的打印之前。 微处理器计算能量值,并与像素能量存储器连接,用于数据的非易失性缓冲,该数据被传送到打印数据控制器并转换成打印脉冲持续时间。

    • In a method and printing device, a deviation from a predetermined desired pitch that occurs between at least two points of at least one print image in a print direction is reduced. In a printing step, the at least one print image is generated on a substrate with at least one print head of the printing device with a relative movement between the at least print head and the substrate. In a determination step preceding the printing step, an initial deviation from a desired pitch between the two points is determined first and correction information to reduce the deviation is determined from the determined initial deviation. In the printing step, control signals for the at least one print head are generated depending on the correction information to generate the at least one print image. A variable delay of at least one of the control signals is predetermined by the correction information.
    • 在方法和打印装置中,减少了在打印方向上至少一个打印图像的至少两个点之间发生的预定期望间距的偏差。 在打印步骤中,至少一个打印图像在具有打印装置的至少一个打印头的基板上产生,该打印头在至少打印头和基板之间具有相对运动。 在打印步骤之前的确定步骤中,首先确定与两点之间的期望间距的初始偏差,并根据所确定的初始偏差确定用于减少偏差的校正信息。 在打印步骤中,根据校正信息产生用于至少一个打印头的控制信号以产生至少一个打印图像。 至少一个控制信号的可变延迟由校正信息预先确定。
