By holding the PITCH button down during power-up, the print pitch can

only be selected from the control panel. This prevents software interference.

After the beep tone, you can set the printer off-line, select a print pitch, then

indicators on the control panel and will not be reset or otherwise changed by

any commands your software may issue.

not be changed by any commands your software may issue.
