The function of the IP Board is to receive host data through one of the following available ports
(USB, or Ethernet). The received host data is buffered and stored and sent to the print engine
in a rasterized format. The secondary function of the I/P Board is to provide print control, Con-
trol Panel control, configuration setup, error reporting, and job recovery.
The IP Board connects to the MCU Board directly. The Control Panel is connected to the I/P
Board and signals pass through the MCU Board via the I/P Board.
