摘要： A thermal printer is equipped with apparatus for allowing the thermal printer to be quickly and easily adapted to the type of paper currently being used without the need for testing and adjusting to obtain an essentially optimum print quality. The printer can also be equipped with a temperature sensor, attached to the thermal print head and connected to the computer control to essentially also produce printed images of uniformly high quality regardless of temperature fluctuations of the thermal print head. The necessary information for providing the adjustment values for producing the high quality print can be stored in a read/write memory connected to the processor. Thus, for each thermal print head temperature, there can be a reference energy value which determines the amount of thermal energy to be generated by the heating elements, whereby the processor, after measuring the thermal print head temperature, selects a reference energy value corresponding to the temperature, and transmits it to the control circuit of the thermal print head.

摘要： A thermal transfer recording and correction method, in which a thermal transfer ink layer is placed in contact with a transfer-receiving medium and is heated by heat generating elements of a thermal head in a pattern corresponding to a recording signal, is improved by preheating the ink layer. The ink layer, which is characterized by a transfer initiation temperature, is preheated by the thermal head which is heated by a preheating means. When a region of the ink layer is then further heated by the heat generating elements, the temperature of that region has a maximum and a minimum both within a range extending from the transfer initiation temperature to about 40.degree. C. higher than the transfer initiation temperature. Since the maximum and minimum temperatures are within a suppressed temperature range, an erroneous image can be more easily peeled off the transfer-receiving medium.

摘要： A method for controlling binary thermal printers increases the effective output resolution of the thermal printer above the native resolution of a print head having a plurality of individual resistive heating elements arranged in a print line. An increase in the effective resolution of a binary output image is achieved by using an over-drive energy to control a relative position of a binary edge of a pixel image at a resolution that is less than the native resolution of the thermal printer. In a preferred embodiment, an under-drive energy may also be used with an adjacent over-drive energy to further control the relative position of the binary image of the pixel image. The over-drive energy is higher than a native pixel drive energy, but lower than a maximum drive energy. The native pixel drive energy produces a binary pixel image having a native area corresponding to the native resolution of the thermal printer. The binary pixel image on the print media corresponding to the heating elements to which the over-drive energy is applied are increased in area beyond the native area of the thermal printer, thereby enabling the thermal printer to realize an increase in an effective resolution of the binary image.

摘要： There is disclosed a thermal printer system having a multiple channel laser print head which focuses closely spaced spots of laser light energy onto a dye donor element which moves at constant velocity relatively past the print head. These laser light spots respectively print multiple lines of an image a swath at a time by heat transfer of pixels or subpixels of dye from the dye donor element to a receiver element. A light source (such as an arc lamp) applies to the dye donor element one or more precisely positioned spots of light energy which elevate the temperature of the dye donor element substantially uniformly within a zone coincidently with and closely surrounding the laser light spots. The shape, the position and the power absorbed within the zone from the light source are carefully controlled. Thus the temperature within this zone is held to a substantially uniform value slightly below the vaporization temperature of the dye to be transferred from the dye donor element. In this way the linearity and fidelity of a printed image are substantially improved, and "printing artifacts" such as banding and streaking are reduced.
