~otice there is a space between each line. This is because the
standard distance from the top of one line to the top of the next is
1 I 6 inch , but a column of graphics is only 1/9 inch high (8 dots x
1/72 inch per dot - 8/72 inch = 1/9 inch). In order to print a
continuou~ image with no gaps between the lines, you must use the
ESC A command to change line height to 8/72 inch and ESC 2 to
achvate the change.
The following program has been modified to give a continuous
image when printing.
