Plot Mode
Description Plot Mode allows you to create and print your own graphics
images. The Plot Mode command must be inside a Graphics
Pass.
Plot data is based on vertical columns of seven dots each. Each
column is described by a hex byte that specifies which of the
seven dots to print. The Least Significant Bit (LSB) of the byte is
mapped to the bottom of the column, while the eighth bit is
ignored. See Table 2.
Command ^Q<plot data>^G
Arguments
^Q Enters Plot Mode
<plot data> The hex plot data.
^G Exits Plot Mode
Example 1: This example prints an X. The command sequence is
^M^Q41,22,14,08,14,22,41^G^-
NOTE: Commas are not required between the data and do not affect the
results. Pass terminators placed between two plot commands will
cause one extra blank dot row to be plotted between the plot images.
To eliminate the blank row, keep subsequent plot commands within
the same pass. To eliminate the blank row, keep subsequent plot
commands within the same pass. Tab and justify commands can be
used to position plot images anywhere in a pass.
