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.

Most are refillable if you follow an unofficial online guide. Beware that toner dust is really nasty stuff and gets everywhere, so however careful you are you'll still have clouds of toner dust escape and stick to every surface of your house inside and out... Top tip:. Never clean toner dust with warm water. It will stick and become permanent.

In any situation where you can see toner you want to be wearing an N95 mask. Inhale any of it and it is in your lungs forever.

The best thing for cleanup is a 3M electronics vacuum which has a filter that will trap that stuff securely.

i’m not buying it. i’ve replaced enough toner cartridges to know there’s significant weight difference between full and empty. it’s a shill article for their industrial CT scanners

I'm so glad I saw your post before rushing right out to buy my own CT scanner in order to save on toner.

You saved me from Big Imaging's clutches.

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.

Well - buy the printer and once it runs out of ink toss it and buy another printer :) I did that with an HP inkjet - got me out of trouble until it ran out, then I replaced with a Brother laser that was half of what the ink refills for the HP would have been. Toner for the Brother is like 20 bucks and lasts for a couple of years given my level of usage.

Years ago I used to do this when I rarely but occasionally needed a printer. Less than $100 for a printer that'd last me 2-3 years then just buy a new one. I fully support this strategy if your usage is really, really low.

Earlier quoted context omitted.

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

I print standard library docs all the time to read. That includes building Table of contents/indexes. I print out pages of source code to do physical cross ref of when I get in some really gnarly code to help me physically reckon through the abstraction spaghetti. I print invoices, letters, diagrams, books, pamphlets. I mean, just because you don't do documents or have anything you want on paper, doesn't mean everyon…

That's crazy. You know the text is just as real if you read it from the screen?

I've never owned a printer, they're Satan's own gift to the consumer electronics market.

Paper is also annoying to deal with. I've had an e-reader for 10 years but the odd older book isn't available. You'd think based on comments online that a real book is some magical wonderful thing, but they're an ass to use, heavy, large to store. Their only virtue is that they look nice on a shelf. But the other thing that looks nice is something other than a shelf.

I remember when I was at school about 15 years ago there were printers that used wax(?) blocks, that were just put into it, not sure how it worked exactly.

Tektronix did a range of printers that used wax. They used rolls of wax sheet. They produced fantastic output, but the rolls of wax were really expensive. And if you put a coffee mug down on a printout, they got stuck together.

I think they were meant for one-off proofs of image-heavy marketing material. The colours were intense and vibrant, in a way that no colour laser or ink-jet ever is. Also, the wax stood a bit proud of the paper, giving an embossed look. But they weren't very permanent - if you folded the printout you'd damage the image; you could even scratch the wax off with a fingernail.

These were expensive printers.

Sounds like you're talking about ink printers, TFA is about laser printers.

Laser printers are far more cost-effective than ink printers, and there are even color laser printers with very decent color quality for everything except photos. (Ink printers are better for photos but even I think those look terrible compared to professionally-developed photos.)

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 p…

Identical story here. The toner the printer came with lasted a few months. I refilled it in a local shop (the guy explained me that they had to replace the chip that counts the pages so refilling was expensive, but in fact it was a fraction of a new one). Still printing with that same toner after (I think) 6 years.

Regarding the brother printer, what do you do with your replacement ink things?

Looks like they market CT scanners. Otherwise I'd ask - why not cut it open instead?

Adam Savage just put out a neat video that featured this company’s CT scanners and software. They scanned two vacuum tube-esque components.
