What do all of the components of a dot a matrix printer do?

I'm doing a project on dot matrix printers. I know all the parts of it, but I don't know what all of them do. Here are the parts I need definitions for: power supply board power transformer main control board paper motor feed home position sensor timing belt printhead assembly printhead positioning motor control panel any help would be appreciated! thanks! dot matrix***

1. power supply board - provides regulated power of different voltages for various components of printer. power transformer - transforms input voltage to a higher or lower voltage required for the power supply to use. main control board - controls the various components of the printer to work together in order to print and to process the incoming data into a format the printer can use paper motor feed - usually a stepper motor that controls how fast and when the paper is advanced home position sensor - detects when the print head/carriage is positioned in a certain location (usually to one side) so it knows where the printhead is to start print on a line timing belt - usually used to move the printhead/carriage in a fixed and controlled motion printhead assembly - the print mechanism that contains the pins that are moved back and forth across the paper and fired at the correct times to create characters using dots printhead positioning motor - the motor that drives the printhead back and forth across the paper control panel - user interface to select and display printer functions and options Best of luck.
