Figure 10-1. Pins numbered sequentially
Each time the print head makes a horizontal pass, it prints a pattern
of dots. To print figures taller than 7 or 8 dots, the print head must
make more than one sweep. If you use the 12-dot (default) line spac-
ing, the print head will leave gaps between the graphics lines, just as it
does between text lines. To avoid such gaps in your pattern, adjust the
line spacing to 7- or 8- dot and print consecutive lines until the figure is
complete. Figure 10-2 shows a before and after example (we work
with this pattern later).
