    Abstract: 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.

    Abstract: 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.

    Abstract: A method and apparatus for maximizing print quality in a thermal printer uses a ribbon condition monitor to detect the condition of a multipass thermal ribbon. Data related to the condition of the thermal ribbon at each individual pixel is used to determine a custom energization signal for each thermal print element. In one embodiment, the system utilizes a history memory to track the prior heating history of each thermal print element and an ink memory to track the prior use of each location on the thermal print ribbon corresponding to the thermal print elements. The data from the history memory and the ink memory are combined to form an index to a table memory containing data corresponding to a plurality of energization signal levels for a particular print medium. The data in the table memory provides the custom energization signal for each of the thermal print elements. In an alternative embodiment, a light source and detector are used to determine the thickness of ink remaining on the thermal ribbon. The energization signal is adjusted to compensate for variations in the thickness of the thermal ribbon. In yet another embodiment, data is encoded at one end of a multipass thermal ribbon. The encoded data provides information related to the amount of usage of the thermal ribbon. The energization signal may be boosted for pixels along the edge of a graphic image so as to maximize the contrast of image edges. The system determines whether a particular pixel is located at the edge of a graphic image area and adjusts the energization signal correspondingly.

    Abstract: A symbology reader uses a linear detector to image a two-dimensional area by scanning the field of view of the linear detector across an image field. In one embodiment, the reader simultaneously decodes data from the linear detector according to two-dimensional techniques and linear and stacked symbology techniques. If the reader identifies a linear or stacked symbology, the two-dimensional processing is interrupted. As the reader scans the field of view of the linear detector across the image field, the scanning mirror simultaneously sweeps a light plane across the image field so that only the imaged region is illuminated, thereby improving the dynamic range of the reader.

    Abstract: A printer for printing on an outer layer of a print medium on a print medium roll. The printer may use thermal or inkjet printing. The printer is used without a mechanical paper drive mechanism. The printer monitors movement of an outer wrap of the print medium as the print medium roll rotates in response to a user pulling print medium from the print medium roll. In one embodiment, the printer detects movement of the print medium with a metering roller and an optical rotation sensor. In another embodiment, the printer monitors movement of the print medium by detecting movement of index marks on the print medium. From the monitored movement of the print medium, the printer identifies a portion of the print medium aligned to the printhead and selects image portions to print in the identified portion. The printer then activates the printhead to print the selected image portions in the corresponding identified portion. A bias spring, together with movable mounting of the printhead, allows the printhead to remain engaged with the print medium as the radius of the print medium roll decreases as the print medium is dispensed.

    Abstract: A system and method for the automatic selection printer operating parameters using a preprinted bar code image on a portion of a selected print medium or a separate sheet of bar code parameters and commands. The bar code image specified characteristics of the selected print medium. A bar code scanner operates in conjunction with a bar code printer and scans the bar code image. The system automatically selects printer operating parameters, such as print speed, print head pressure, and burn duration to configure the printer for optimal operation with the selected print medium. The bar codes can also be used for test and service, label design, data entry, or work in process.

    Abstract: A method and apparatus for convenient and easy access to product- and shipment-related information and/or transactions is disclosed. A radio frequency tag reader is used to read a radio frequency tag having a structured data format. The end device parses one or more particular data entities from the data read. The radio frequency tag reader accesses a URL having at least a portion in common with one or more of the parsed data entities and displays associated web page content or processes an associated transaction. The radio frequency tag reader may sequentially substitute a series of most probable non-common URL portions to locate associated content if the first tried URL does not result in a valid response. Alternatively, a server may provide such search functionality.
