Selecting character spacing

This function selects one of the fixed spaced characters and proportional spaced characters. The "Pitch Lock" option in the extended setup options can lock-in the character spacing selected in this option and ignores the related software command.

When SD (speed draft) or SSD (super speed draft) is set the character spacing automatically changes to 12 cpi or 15 cpi, respectively.

When OCR-A or OCR-B font is selected, either 10 cpi or 12 cpi can be selected.
