Figure 4. Odd Dot Plot Data Example
In odd dot plot, the (cc)G terminator causes the contents of the
buffer to plot and advances the paper a single dot row based on
the vertical density of the current print mode. In even dot plot, the
paper/printhead is not advanced.
For high density plot, the Even Dot Plot and Odd Dot Plot
commands are used in conjunction with two data lines. The Even
Dot command is sent with the first data line along with the (cc)G
terminator. The terminator causes the contents of the buffer to
plot in the even dot columns but does
not advance the paper/
printhead. The printer waits for the second line of data using the
Odd Dot Plot command and a terminator. Data in the buffer is
plotted in odd dot columns of the same row where even dot
column data was just plotted and the paper/printhead is
advanced one dot row at the vertical density of the current print
mode.
Example The following sample command illustrates plotting, by plotting a
line of arrows using the data shown in Figure 4.
