The printer industry needs a revolution.

Does it? It’s a dying industry. When was the last time you printed anything?

It is dying but very slowly, still very profitable and pretty big business. hp's 4th quarter printing business was 4.5 billion with a 20% profit margin.

Never, ever, ever buy a printer that takes cartridges. They’re discounted to at or below cost where they make the money back on cartridges. They use ink to clean the heads. They say empty when they’re not. The cartridges that come with the printer aren’t full. There is a constant firmware update war to defeat third party cartridges for obvious reasons. Buy a tank printer that you fill with ink bottles.

Earlier quoted context omitted.

Inkjets have to be used regularly or they will suffer from clogs and in the case of Epson you're SOL if a head clean doesn't work. You can leave a laser idle for years and it will print fine.

I think eco tanks (and some other modern inkjets) will purge the heads regularly if left on, so it should be fine if left on standby constantly.

Mine doesn't, some nozzles clogged every time I wanted to print (infrequently, sometimes months). Now I'm printing a test page every week to prevent that (maybe should add a cron job).

A contributing factor could be that the best-before date on the bottles is in the past. Though I have no idea how that date would matter for filling up, and no idea how to observe it after the ink is in the printer and the bottles disposed of.

Manufacturers want to provide a product that produces reliable high quality prints. That's why the toner low warning comes up very early, so that there's no chance that your important documents look unprofessional due to low toner levels. As a consumer, naturally, you can almost always ignore the warning and use the toner until you can't even read granny's apple pie recipe anymore.

This is being a bit too generous. If that were the case, they could provide a warning about print quality instead of just saying that the toner is low. But then people wouldn't be as compelled to needlessly buy more overpriced printer supplies.

If you have a Samsung laserprinter with number pad and empty toner / imaging unit try menu # 1904 menu and reset the counter, then happily print thousands of pages more

I bought a Samsung printer a few years ago. A couple of months later, I discovered that Samsung's printer arm had been acquired by Hewlett-Packard - the company I least wanted to buy a printer from.

My printer has no number pad. It has a horrible menu system you navigate with arrow-keys. The cartridge it came with was tiny - it lasted for less than a ream. But the replacement I bought is still going strong (I don't print more than a couple of pages a week, which is why I didn't want an ink-jet).

I have a Brother laser printer which is used for almost everything, and a Canon inkjet for the occasional color print.

I’m pretty sure my Canon inkjet uses more ink when idle than when I occasionally use it to actually print something. Quite sad.

I do wonder where it all physically goes tho. After years of seeing my cheapo cartridges just “evaporate” whatever reservoir the printer has for cleaning the heads and purging ink must be well and fully saturated at this point?!

I would like to see cartridges designed ecologically - refillable perhaps, or at least designed to flow as much out as possible - and allowing you to override the "toner low" warning and keep printing even if it's almost dry.

> refillable They used to be in some applications (like really big photocopiers). But toner is messy nasty stuff to deal with. Maybe refillable at a shop could work though.

I've been refilling the toner cartridges for my low-end Brother printer with generic toner off Amazon for years. It's not that bad and costs a fraction of the price of even a generic replacement cartridge. The toner comes in a bottle and you slowly pour it into the cartridge, perhaps with the assistance of a small funnel if necessary. I wear gloves and do it outside or in the garage. It only gets messy if you try to do it inside or have the dropsies. Obviously don't breathe it in.
