This chapter uses the term dot positions instead of dots for two densities: high-speed double and quadruple. Because the FX-286 does not print consecutive dots in a row in these densities, it cannot print dots in all the possible dot positions in any one row. For example, an eight-inch high-speed double-density row has 960 places where the 6-9

This chapter uses the term
dot positions
instead of
dots
for two
densities: high-speed double and quadruple. Because the FX-286 does
not print consecutive dots in a row in these densities, it cannot print
dots in all the possible dot positions in any one row. For example, an
eight-inch high-speed double-density row has 960 places where the
