05H — Odd Dot Plot
For odd dot plot, the data line contains the odd dot plot control code (05H ),
the data bytes, and the terminator.
The first data byte represents the odd dots to be plotted in character column
1, and the last data byte represents the odd dots to be plotted in the highest
numbered character column used. When the terminator is read, dots print in
odd dot columns and the paper advances.
Line Terminators
Odd dot plot line terminators are 0AH (Line Feed), 0CH (form feed), and
0DH (carriage return). The printer will default to character printing after
each plot line unless you include the control code for plot within the next
data line.
Graphics and character printing can be combined on the same page, but not
on the same line. It is possible to produce special characters by plotting their
dot matrices, but this method is less efficient than creating a special character
PROM.
With Configuration Option 43
Depending on the setting of Configuration Option 43 (plot exit) when the
transition from plotting to character printing is made, adding another line
feed (LF) to the last terminator may be necessary. When you use 43.0, an
extra line feed is needed to maintain line registration throughout the page,
and to avoid the possibility of truncating the top of the first character line
after plotting. Configuration Option 43.1, does not require an extra line feed
because it is automatically included.
Refer to Figure 5–11 on page 5–22 to see an example of a truncated character
line compared to a normal character line.
