The InfoPrint 6500-D 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 12.
