    • The presence of a radio frequency signature (88) on a cut sheet of print media (28) is detected by a radio frequency interrogating device (94) to determine it's relative left/right position on the print media (28). Either the leading edge (124) or trailing edge (126) of the print media (28) is detected by one or more print media sensors (86, 90). A print controller (24) can note the time (t1) when print media is detected and cause the radio frequency interrogating device (94) to detect the radio frequency signature (88) at a time (t2) when the print media has reached a predetermined point along the print media pathway (110). The position of the radio frequency signature (88) on the print media (28) can be calculated using the time differential (t2-t1) and the known angular displacement of the radio frequency interrogating device (94).
    • 通过射频询问装置(94)检测在打印介质(28)的切片上的射频签名(88)的存在,以确定其在打印介质(28)上的相对左/右位置。 打印介质(28)的前缘(124)或后缘(126)都被一个或多个打印介质传感器(86,90)检测到。 当检测到打印介质时,打印控制器(24)可以记录时间(t 1> 1),并且使得射频询问装置(94)一次检测射频签名(88) 当打印介质已经到达沿着打印介质路径(110)的预定点时。 射频签名(88)在打印介质(28)上的位置可以使用时间差(t 2 -T 1 -T 1)和已知的角位移 的射频询问装置(94)。

    • A radio frequency signature (88) on a cut sheet of print media (28) is detected by a radio frequency interrogating device (94) to determine whether the print media (28) is properly oriented. The leading edge (124) or trailing edge (126) of the print media (28) is detected by one or more print media sensors (86, 90). A print controller (24) can note the time (t1) and cause the radio frequency interrogating device (94) to detect the radio frequency signature (88) at a time (t2) when the print media has reached a predetermined point along the print media pathway (110). The position of the radio frequency signature (88) on the print media (28) can be calculated using the time differential (t2−t1), the velocity profile of the print media and the known separation between the print media (28) and the radio frequency signature (88). By comparing the computer position with the expected position, the orientation of the print media (28) can be determined.

    • A printing system (250) includes a printing subsystem (255) in the form of a printer assembly (14). The printing subsystem (255) includes a printer housing (257) in which a print engine (259) resides and (261) for storing data indicating the position of labels on media. The contents of memory (261) can be obtained from an end user application (270) which may supply the position data to the printing subsystem (255) in a print data stream. Pre-programmed position data is read from a tag (88) on print media (28) having multiple tags embedded thereon. The pre-programmed position data is compared to position data received in a print request data stream to determine the position of at least one tag on the print media.
    • 打印系统(250)包括打印机组件(14)形式的打印子系统(255)。 打印子系统(255)包括打印机外壳(257),打印引擎(259)位于其中,(261)用于存储指示介质上标签位置的数据。 存储器(261)的内容可以从可以在打印数据流中向打印子系统(255)提供位置数据的最终用户应用(270)获得。 从在其上嵌入有多个标签的打印介质(28)上的标签(88)中读取预编程的位置数据。 将预编程的位置数据与在打印请求数据流中接收的位置数据进行比较,以确定打印介质上的至少一个标签的位置。
