HI Avi,

A simple explanation is that a printer receives information from a computer and turns that into a graphical representation using an image processor. From there the printer uses mirrors to reflect light off the parts of the paper that ink will be applied. The purpose of this is to create positive electronic charges that cause the ink to stick to the paper. Toner is then applied to the page in line with the graphical representation the printer received from your computer. You can find more information here:
