This adaptable interface method for a line-of-dots thermal printer provides ease and flexibility in attachment for many low-end copy and printing requirements. In a display screen copy application, this interface will accommodate a wide range of display timings, allowing a single thermal printer product to be attached to a variety of display products. The interface uses six data and control signals to provide the data and control for direct loading of print dot information into the shift register buffers of the printer. The buffers are loaded serially with one buffer position for each print dot. When a complete line of print dot information has been stored, the interface applies a strobe to gate the buffer contents to the printhead. Fig. 1 illustrates this interface in a display attachment.
