The example above, which only holds true for the 12 cpi mode, shows the full dots as adjacent to each other in the character cell. The 10 cpi mode allows a gap between adjacent full rows; 17 and 24 cpi allow an overlap of full rows. The printer cannot print adjacent full and half dots in any single row. Some graphics (double-density, half-speed) allow adjacent rows to be printed by slowing the print speed by half. Slowing the print speed allows the time between half and full columns to be the same as the time between full columns in full-speed operation.

The following illustration shows the use of full and half dots as well as descenders to form characters.
