In this program, line 20 assigns the graphics option (24-pin triple- density) with code 39. Code 42 sets the number of pin columns at 42. Lines 80 through 140 contain 126 bytes of data (42-pin columns x 3 bytes) for each pin column. Lines 30 through 60 print the design that you see below.

Notice that the dots overlap quite a bit. This design was printed using the triple-density, 24-pin graphics option because the density is the same (180 dots per inch) in both directions.

Adding the following lines to the preceding program causes the pattern to print 10 times in a row as shown below.
