ah, but wait, there's more!
My partners previous ink tank printer (canon) one day stopped working, because the "ink pads are full".
which means no printing AND NO scanning either.
They finally found out the ink pads are super cheap.
BUT,once swapped, you need a reset code to get it working again.
And guess what THAT costs?
Yes - the opposite of "cheap" (you either pay some "authorised dealer" for a code,or you pay for the software that generates the key - either way, you cough).
