is for ink -
As a user of inkjet and bubblejet printers I shuddered at the prices for the consumables - those little "jewels" we buy to keep printing. Now I order"pint" bottles (that's 450ml) of ink from a family business in the US who specialize in "Odd Parts." Their web site is full of interesting mechanical and electronic bits and BULK INK for most brands of printers.
use a Canon colour printer which has 4 x $20 separate ink
Clicking here can get you to the "Bulk Ink" web site in the US. It has detailed instructions for refilling many models of printer. There's another reason it costs so much less - no packaging cost. Just download the instructions for your brand of printer.
