♦ Mechanism driver board
♦ Hammer driver board
♦ Power supply
♦ Print mechanisms
Figure 2–9 is a block diagram of the functional elements of printers

Figure 2–10 is a block diagram of the functional elements of printers
controlled by the LMI.
The rest of this chapter discusses these systems in more detail.
