The main component in a printer that acts as the motherboard is the printer controller. This large circuit board is responsible for managing all the mechanical and electrical functions of the printer.

When it comes to laser printers, the printer controller plays a crucial role in various processes. It oversees the creation of a photoconductive image on the drum using a laser, the attraction and transfer of dry ink particles (toner), and the fusing of toner onto paper using heated pressure rollers.

While the imaging drum is essential in receiving the photoconductive image and attracting toner, it is not a circuit board like the printer controller. The toner cartridge contains the toner powder for printing but does not act as a motherboard. The maintenance kit includes items for printer upkeep but does not serve as a circuit board for operation.
