Inkjet printers spray the ink highly accurately, and directly onto the paper. Laser printers lay consecutive layers of different colours on the paper and then fuse them using heated rollers at the end of the printing cycle (as the paper exits the printer). The colours are the same (CMYK) but require different paper technology in order to absorb them and make them permanent at the end of the printing process. While Laser printers use a micro polymer powder (toner) as the colour medium, inkjet printers use liquid inks.
Both technologies mix four base colours (Cyan, Magenta, Yellow and Black) to create the wide gamut of possible colour, but this is where the similarity ends. Laser and inkjet printing technologies are totally different, yet use the same principles in generating colourful images on paper.
