0DH — Carriage Return Control Code 0DH causes the logical print head to move to the left margin
without any motion or printing activity. Therefore, to initiate printing you
must send a line feed with the carriage return. If you send configuration
Option 23 for line feed on carriage return, the buffer contents will print
when a carriage return is sent.
With Configuration Option 23 and 28
If you set Configuration Option 23 to 23.0 (CR=0 line feeds), the carriage
return will not cause printing, and therefore, the underlining feature
(Configuration Option 28) will function properly. However, printing will be
delayed until you add underlines to the buffer in the desired character
positions.
When you load the buffer with characters and underlines, printing will begin
with the next line feed when sent by the host computer. This activity will
result in a line printed with the appropriate characters underlined as shown in
Figure 7–3. See page 7–14 for a complete description of the underline
function.
