At the time of purchase you can find these things out by researching the price of the replacement ink cartridge and its page rating. (Page rating is soft/fudgeable but should at least be a reasonable way to ballpark the lifespan of the cartridge.) I would consider this cursory research when evaluating a purchase that takes an ongoing supply of consumables.

To me it sort of seems like you're saying "Wow this dryer uses way more electricity than I thought it would!" or "Wow I bought this razor handle and the blades are really expensive!" or "Wow Swiffer really screws you with the replacement wipes!" or "Wow this car takes expensive tires!" -- even though the numbers for the ongoing consumables were available at the time of purchase.

So every time I buy a swifter or razor or dryer I have to do thorough research on things like power consumption, cost of replacement parts etc. No! I have a life, I have other things to do. I buy from large brand names like Lexar because I expect them to be honest and engage in fair dealing and because researching every aspect of products I buy would be a full time job in itself.

I get where you're coming from, but this concept you take issue with goes by another name: "due diligence"

I'd even argue that selling a cheap ~$50 printer and then expecting to make it back on consumables is a legitimate business model. If you're the kind of person who prints once in a blue moon, it makes more sense than buying a ~$200 laser printer.

Printers are generally expensive and generally last a few years. They're not casual, off-the-cuff purchases. Much like a computer, they are a precision machine, but with many more moving parts. I really don't believe it's unreasonable to do a couple hours worth of research on something that'll be in your home or office, possibly doing Important Serious Business Things, for years.

Actually if you print that infrequently you'd probably be better off with one of those 'office stores' as a print service.
