I don’t think it comes as a surprise that printer ink grossly overpriced. This seems to be the case whether you’re purchasing ink for your home office printer or ink for your photo printers. For example, a set of 11 UltraChrome inks for the Epson 9900 wide format printer will set you back at least $800. Paying that kind of premium, consumers want to make sure they aren’t letting any of that precious liquid gold go to waste. Unfortunately, every time your printer notifies you it’s time to replace an ink cartridge, you’re probably throwing out hunderds of dollars worth of ink.
“On average, when we throw away a cartridge of ink from our Epson 9900 printer, we throw away well over 100ml of ink. Many times 150ml or more. But, on average, we throw away 120ml of ink with every 700ml cartridge and about 60-80ml of ink with every 350ml cartridge.”
