The other user is incorrect; it's actually 1. <u>Dot-Matrix Printers</u>, and 2. <u>Thermal Printers</u>
Explanation:
Thermal printers (as the name suggests) use heat to print objects. Think of these like reciept printers or what you get when your school ID is printed out; when you grab it right away, the dye is still warm.
Dot-matrix printers print at lower resolutions and are standardly used for text. I'll give you an image example of what the text looks like for the dot-matrix printer and the thermal printer.
No, you should let them make the choice on their own but encourage them in their decision I think and encourage them to try new things even if their afraid\ of them like stage fright :) Hope this helped at all :)
An optical illusion is a way of art. Optical illusions give motion even though the art is not moving. I would make a bunch of waves then perfect shading to highlight the motion of the waves. HOPE THIS WILL WORK.
