I've got the Instant Ink plan too. A couple of things to watch out for - despite what it says, it does charge by the amount of ink used and not by the page. If you are printing text from Word, say, you are fine, but if you print out a page that has pictures or boxes, that will use up much more ink, so is classed as several pages. That means that printing out a report with lots if graphs and detail can quickly eat up your entire monthly ration of pages. Also, I found I was always running out of ink at first. New cartridges are automatically posted out to you when the ink is running low but they weren't being sent early enough and then when they did arrive, they'd be too big for the letter box and so I'd have to go to the sorting office to pick them up. HP sent me a few to have in reserve, so that is all OK now. On the plus side, colour printing is no more expensive than black & white and the plan has saved me money overall (especially now that I think twice before printing out reports).
