ABSTRACT:
In a controller for use in a printer, when line pitch information is set in a printer status storage unit by way of a line pitch setter, a distance setter determines a cursor/base line distance on the basis of the line pitch information, and a character pattern expander determines a base line from the cursor/base line distance, expands a dot pattern of a printing character in reference to the base line position and stores the expanded dot pattern in a buffer memory.
