    • An apparatus, such as a printer or reader receives a data stream from a memory, such as from an RF or photonic memory, and compares portions of the data stream to a table of data. If a portion of the data matches an entry in the table, a corresponding entry in the table causes the apparatus to be automatically configured. Alternatively, an apparatus receives a data stream to be written, such as in a bar code symbol or tag memory. The apparatus analyzes portions of the data, comparing portions of the data to a reference table. If the apparatus identifies a match, the apparatus adjusts the writing of such data. For example, the printer writes a portion of the incoming data stream to both fields in a bar code symbol and in a portion of the memory in an adjacent RF readable tag.
    • 诸如打印机或读取器的装置从诸如从RF或光子存储器的存储器接收数据流,并将数据流的部分与数据表进行比较。 如果数据的一部分与表中的条目相匹配,表中的相应条目将使设备自动配置。 或者,装置接收要写入的数据流,诸如条形码符号或标签存储器。 该装置分析数据的部分,将数据的部分与参考表进行比较。 如果装置识别匹配,则装置调整这种数据的写入。 例如,打印机将输入数据流的一部分写入条形码符号中的两个字段以及相邻RF可读标签中存储器的一部分。

    • A dual technology printer includes first and second print stations having a polychromatic print engine and a monochromatic print engine, respectively. The print engines are preferably an ink jet print engine and a thermal print engine. A variable length media queue is formed between the two print stations. The queue may be formed by a guide roller that defines a loop of media between the stations and that is movable to adjust the length of the loop and thereby the length of the queue. Preferably, the second print station has a predetermined pixel addressability and a resolution substantially equal to the addressability to produce sharp borders for machine readable symbologies. In a printing operation, the printing of color images at the first print station may be carried out ahead of demand for a particular batch printing operation during which monochromatic images are printed at the second print station.
    • 双技术打印机包括分别具有多色打印引擎和单色打印引擎的第一和第二打印站。 打印引擎优选地是喷墨打印引擎和热打印引擎。 在两个打印站之间形成可变长度的媒体队列。 队列可以由引导辊形成,该引导辊在站之间限定介质环,并且其可移动以调节环的长度,从而调整队列的长度。 优选地,第二打印站具有预定的像素寻址能力和基本上等于可寻址性的分辨率,以便为机器可读符号产生锐利的边界。 在打印操作中,在第一打印站处的彩色图像的打印可以在特定批次打印操作的需求之前执行,在该打印操作期间在第二打印站打印单色图像。

    • A printhead having multiple print lines of conventional design and a printhead control system for using the multiple print lines in a variety of operations. In one embodiment, the printhead control system prints an image by superimposing the printing from multiple print lines. In another embodiment, the image is printed by alternating the energization of one print line so that each print line is used to print only ⅓ of the image lines. As a result, the print lines are allowed a relatively long time to cool, thus allowing the printhead to be operated at a faster speed. In another embodiment, the printing elements of each print line print with a different image density, and images printed by superimposing the printing elements in the print lines with a variety of combinations depending upon the desired magnitude of the image density. In still another embodiment of the printhead control system, the resistance of each printing element is checked and, if found to be unacceptably high, corresponding printing elements of other print lines are used for printing.
    • 具有多个常规设计的打印线的打印头和用于在各种操作中使用多个打印线的打印头控制系统。 在一个实施例中,打印头控制系统通过从多个打印行叠加印刷来打印图像。 在另一个实施例中,通过交替一个打印行的通电来打印图像,使得每个打印行仅用于打印1/3的图像行。 结果,打印线允许相对长的时间冷却,从而允许打印头以更快的速度运行。 在另一个实施例中,每个打印行的打印元件以不同的图像浓度打印,并且通过根据图像浓度的期望大小以各种组合将打印元素叠加在打印行中来打印图像。 在打印头控制系统的另一个实施例中,检查每个印刷元件的电阻,并且如果发现其不可接受地高,则使用其它印刷线的相应印刷元件进行印刷。

    • A printer for printing on a manually moved print medium. The printer may use thermal or inkjet printing and has user feedback and input. A roller-type position detector enables the printer to be used without a mechanical paper drive mechanism. The printer monitors the print medium as the print medium is propelled through the printer to identify when particular printing fields are aligned to the printhead. The printer then activates the printhead to print image portions in the printing fields. An alternative embodiment of the printer uses a flexible mounting of the printhead. In this embodiment, the paper roll diameter is determined in conjunction with monitoring the rotation of the paper roll to determine the position of the paper without requiring a roller-type position detector.
    • 用于在手动移动的打印介质上打印的打印机。 打印机可以使用热敏打印或喷墨打印,并具有用户反馈和输入。 辊式位置检测器使打印机能够在没有机械纸张驱动机构的情况下使用。 当打印介质通过打印机推进时,打印机监视打印介质,以识别特定打印区域是否与打印头对齐。 打印机然后激活打印头以在打印区域中打印图像部分。 打印机的替代实施例使用打印头的灵活安装。 在本实施例中,纸卷直径与监视纸卷的旋转相结合来确定纸张的位置,而不需要辊型位置检测器。

    • An apparatus for use in a thermal printer for printing information onto a paper substrate material is provided. The apparatus enables the thermal printer to compensate for the variable payout force of the paper substrate material. The apparatus comprises a platen in contact with the paper substrate material at a print region of the thermal printer. A motor and a roller mechanically coupled to the motor are used to transport the paper substrate material through the print region. A rotational rate detector comprises a light source, a disk having alternating radially disposed regions of different light conductivity, and a photodetector adjacent to the disk. The disk is at least partially illuminated by light provided by the light source and the photodetector to provide an electrical signal corresponding to detected periodic changes of the light illuminated onto the disk during rotation of the disk in cooperation with the platen. A central processor is adapted to receive the electrical signal and provide a driving signal to the motor. The driving signal compensates for the variable payout force by altering a corresponding transport rate of the paper substrate material in accordance with the detected rotational rate of the disk, an event model stored in a RAM, and/or a harmonic model stored in the RAM.
