During each sweep of the shuttle, the hammers print dots at the required
positions in the dot row. When the shuttle reaches the end of a sweep, it
reverses direction, the paper is advanced one dot row, and the hammers print
the next row of dots as the shuttle sweeps in the opposite direction. (See
Figure 1–3.)
After a line of characters is printed, hammer action stops while the paper is
advanced to the first dot row of the next print line. The number of rows
allowed for line separation depends on the line spacing you select.
