Character Formation
The IBM 6400 is an impact printer: it creates characters by printing ink dots on
paper. Dots overlap to produce a solid–appearing character of uniform
density. The dots are made by an assembly of steel hammers mounted on a
rapidly oscillating shuttle. The hammers strike the paper through a moving ink
ribbon. The dot patterns of characters are mapped in printer memory on
invisible matrices, as shown in Figure 73.
