You can take any picture and print it over multiple pages. This could work for large classroom puzzles, improving sequencing skills, math calculations(area, perimeter), larger prints, etc. You pick the number of pages you want your picture to span and it creates the file for you to print. Print the file, put it together and shezam you have a poster. I wouldn’t use it to much because of the amount of ink it would use, but for those occasional purposes this could be very handy.
