Latest Patents

One of Trackman's latest patents is for a multi-line serial printer. This invention allows for a predetermined window height that is at least three times the height of normal printed characters to be printed in a single horizontal sweep of the printhead across the page. The process involves sorting character-oriented data vertically and sequentially processing it into a 'print window' of horizontally sorted characters. The average throughput is increased by allowing the printhead's velocity to vary based on the complexity of the image formation process. Additionally, for thermal processes, adjustments in the current passing through the activated printhead electrodes are made. Another patent focuses on means to inhibit paper feed during carriage or print wheel movement in a daisywheel printer. This invention utilizes carriage control and printwheel control signals to operate inhibiting apparatus for a control signal that would otherwise be gated to a paper feed operator.
