We all know printer manufacturers more or less give away their printers and make their money selling their paper and ink.
Canon is no exception.
The ink cartridge contains very little ink (few CC.) and cost the price of gold.
I have a Canon PIXMA MP-150 and have been using it for several years with Canon paper and Canon original inks.
Very frustrating when the cartridges come to an end and you have to fork out nearly as much as the original purchase price of the printer to relace them.
I never quite understood why in some cases it was cheaper to buy a new printer with cartridges than simply buying the cartridges...
I ended-up a couple of years ago, with a few spare brand new printers with no cartridges...!
So it was a really pleasant surprise to have discovered the HIGH YIELD CL51 colour catridge !
Because at a price of 30% extra or so, (compare to the "normal" CL41) it gives much more results than twice the quantity of printing.
It last much longer, and does not dry out.
I am convinced that if one tries the CL51, it will have an everlasting result that will make one never buy any other cartridge again....
