A thermal printer, which has a resistive ribbon and prints predefined characters and graphic symbols from font modules through selectively energizing electrodes arranged in a column for transferring heat to the ribbon, can be used for all-points-addressable (APA) printing through controlling when each of the print electrodes may be activated during various passes of the electrodes along the same printed line relative to the recording medium. A thermal printer having forty electrodes, which are spaced on 1/240" centers arranged in a column, may be utilized to print graphics supplied from eight bits of data and previously used with a printer having nine electrodes spaced on 1/72" centers.
