Exposing, the image is applied to the negatively charged drum with a laser. , Step 4. Developing, the toner is attracted to the drum in the areas with a charge, Step 5. Transferring the toner is transferred to the paper, Step 6. Fusing the toner is fused, heated and pressed to the paper. 7. Cleaning the printer is cleaned.

Piezo electric and thermal bubble
Thermal printer
Applies heat to special paper
very inexpensive
