Waste - something used inefficiently or inappropriately.

I researched the amount of ink being left in the cartridge after it has been changed with a new one.
My research shown that majority of printers leave 8% of an ink which is equal to 1.5milliliter of an
normal size cartridge. I decided to use what's been left and show it by printing off these typographical
posters,how many pages it is still possible to print, before your printer just stops.

In total there are 17.5 posters.
