    • A printing apparatus for printing within a predefined print zone on a selected surface of a skewed object moving in a given direction of travel includes a bracket, at least two sensors at known positions adjacent to the passing object detecting the leading edge of a given surface, a positioning mechanism mounted on the bracket, a printhead mounted on the positioning mechanism and operable to print on the moving object selected surface, the positioning mechanism operable to position the printhead into a known correct printing position relative to the selected surface, and a controller communicating with the sensors, positioning mechanism, and printhead, and operable to calculate object skew in response to the sensor signals and to operate the positioning mechanism to position the printhead into the known correct printing position and to operate the printhead to print within the predefined print zone on the skewed moving object.
    • 用于在给定行进方向上移动的偏斜物体的选定表面上的预定打印区域内打印的打印设备包括托架,在与检测给定表面的前缘的通过对象相邻的已知位置处的至少两个传感器, 安装在所述支架上的定位机构,安装在所述定位机构上并可操作以在所述移动物体选择表面上打印的打印头,所述定位机构可操作以将打印头相对于所选择的表面定位在已知的正确打印位置,以及控制器通信 传感器,定位机构和打印头,并且可操作以响应于传感器信号来计算物体偏斜,并且操作定位机构以将打印头定位到已知的正确打印位置并且操作打印头以在预定打印区域内打印 在偏斜的移动物体上。
