Definition: Powder used in laser printers and photocopiers to form the text and images on the printed paper.

Alright class, settle down, let’s take a look! Today we’re tackling “toner,” it's quite a word, you see. The dictionary tells us, perfectly clear to me: “Powder used in laser printers and photocopiers, To form the text and images – what writers desire!” Now, let's break that down with a little rhyme, It’s like tiny particles, keeping things prime! Think of it this way: When you print a page, This powder sticks, engaging in a stage. Laser printers use beams to make the light, And toner clings on, oh so bright! Photocopy machines, they need a treat, To build those pictures, wonderfully sweet. It’s essentially dry ink, but with a special key, To create your words for all the world to see! Do you have any questions about this little bit of science? Raise your hand if you're feeling keen!
