Print head modulator. |
摘要 |
<p>A thermal print head modulator (300) for generating modulation signals for printing a halftone dot (145) whose size corresponds to a data value (205) represented by a plurality of bits. The modulator (300) includes a programmable look-up table (235) containing modulation values (236) that are selectable by control circuitry (245). By storing modulation values (236) in a pre-determined pattern and selecting each value sequentially for comparison with each data value (205), the modulator (300) is compatible with both pulse count modulation and partial pulse modulation having any number of designated partial pulse bits in the data value (205). <IMAGE></p> |
