Canon - CLI-42 8-Pack Standard Capacity Ink Cartridges - Black/Cyan/Gray/Magenta/Yellow

This is the correct INK. You do get points.Don't use compatible ink.

No, any product look up will tell you that you need CLI 65 cartridges for the Pixma Pro 200

I've left the cartridges set unopened on the shelf for over 1 year. I've had them installed in the printer for over a year...BUT... when the cartridges are in the printer I turn it on every 4-6 weeks, let it cycle, then turn it off. This helps keep the ink in the nozzles from drying and clears them. Yes it uses a bit of ink, but that's cheaper than head repair or replacement.

New with printer 28g Refills 27g Based on what I've heard and info found online. Not much difference and NO, I don't know why unless Canon puts a touch extra in the new with printer carts to make up for the initial charge of the printer system.
