    摘要: 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 1/3 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.

    摘要: A system for controlling the temperature of the printing elements of a thermal printhead. The printhead is provided with a plurality of spaced apart temperature sensor that measure the temperature at various locations on the printhead. A processor receiving outputs from the sensors determines the approximate temperature of each printing element based upon its proximity to at least one temperature sensor and the temperature sensor outputs. The processor then uses the approximate temperature of the printing elements to formulate either a strobe signal or a serial data stream that is applied to the respective printing element. Each printing element thus receives a quantity of energy that is a function of whether the printing element will contribute to the printing of an image during a scan line as well as the approximate temperature of the printing element.

    摘要: 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.

    摘要: 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.

    摘要: 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.
