Selected Print Mode and Pitch: DP 10 cpi

DP 10 cpi with descenders = 12 Columns x 9 bits per column (Table E-2) Figure E-2. Characters with Descenders Layout

The BASIC program to generate this character and a print sample is provided below.

The command for the character shown in Figure E-2 is as follows:

ESC c {00}{90E}{2};{0;0;0;72;88;7;88;72;0;0;0;0;}

where:

ESC c is the Serial Matrix Control Code Header introducing the Download a Character command.

{00} is the selected print mode and pitch code from Table E-2 derived from Print Mode/Pitch Selection Table 6-7 on page 6-59 m = 0 representing DP mode; and n = 0 representing a pitch of 10 cpi.)
