Inkjet paper is special paper that is made to work really well with printers that use ink cartridges. You know how you can draw a picture with markers on regular paper, but sometimes the marker doesn't show up so well or smudges? Well, inkjet paper is made so that the ink from the printer stays put and looks nice and clear. It's also a bit thicker and absorbs the ink better, so the colors come out looking really nice and bright. So, when you want to make a cool picture or print out a book report or something, you can use inkjet paper and your printer to make it look really nice!
