Always have been, though I hope they're better than the crappy 9-pin dot-matrix rubbish they used to peddle.

Dot matrix printers are worth a mint if you have them.
Put it on e-bay. A lot of small businesses still use carbon copy, and inkjet and laser don't work on that.

But only if it's a good quality one, not Epson. Epsons virtually arrive broken in the box from the factory.

Try working in an office with four DECwriters (LA120) which supported the printing needs of a small office building.

It builds character, no? 
Was anyone there approached by the CIA? Being immune to torture would be a plus for that profession.

The office was also kept at 50F, the same as the adjoining computer room.
I can say no more.

The CIA recruited those who specified the DECwriters for that office, and kept it at 50°F (10°C). Everyone eventually breaks under torture, but torturers who have no empathy for their victims are really hard to find.

I had a Epson 9 pin for years very long ago. Worked as long as I had it. I don't recall any problems. Never needed service and I wasn't even taking care of it that well.
Still working when I upgraded to a HP Laser which I only did so for the print quality. That HP Laser also lasted for years until I upgraded for color.

Never had a problem with my old LQ-850, WAY back in the day.

I found Epson to be one of the better inkjets, with no feed problems unless you use the really cheap / thin paper - I switched to 90gsm as my standard and never had a problem with jams.
What I hated was the half an hour clean / purge / test print / swear cycle I had to go through each time I needed to print, plus the Epson fun and games of cartridge expiry / not recognised. So I threw it to the recycle centre and got a Samsung laser which I plug in, print, and unplug - it works every single time and it prints faster. I think it's cheaper to run as well given how many ink cartridges I binned.

This is what I ended up doing as well, except I made the mistake of buying an HP laser. Overall, I'm happy with it, just dumb that when you scan it goes to the "cloud" and emails it back to you...

I really wish you weren't kidding ... 
Mine no longer has a scanner - the "Documents" setting on my phone does good enough for me. The last scanner / printer was an Epson and it annoyed me because it wouldn't scan unless it had ink in all cartridges. Another moment.

My guess is that rather than have firmware on the printers that checks for copyright infringement and trying to copy money, they check it server side when it goes to the "cloud".
I've seen the option to scan documents with my phone, I'll have to give that a shot in the future

Nope, all scanner / printers have built in "money detectors" to prevent them working like a photocopier ...
Apparently with some models, just trying will deliberately brick them.
I found out about this when Herself had a thief at work: I wanted to OCR all the paper currency in her purse so if it went missing we could say "it was these serial numbers" and nick the cow who did it. But you can't scan currency and I wondered why. Google "EURion Constellation" if you are interested - it's pretty simple, but very effective.

So that's what it's called. I work in printing and some of our educational work has them in there to prevent photocopying. We actually had a complaint on Amazon about a book we printed. Turned out it was a knockoff, lol.

I had to fix a printer for a friends mother a few weeks ago - simple fix, just press "OK" on the printer - but first I had to cancel the 83 copies of the same document in the print queue ...

tl;dr
A bad cable on a parallel dot matrix printer caused a still unexplained error that cost two days of frustration to disagnose and correct.
Years ago I spent a weekend helping a client install new accounting software and uploading their financial data from the old system. On Sunday we printed all their financial statements and compared them to the reports they had printed on Friday. Everything was good.
Two weeks later they gave me a call. The balance on one of their monthly reports was out by 10 cents. The balance was supposed to be $15,260.00 and it appeared that way on screen. The printed balance showed $15,260.10,
I could not find anything wrong with the software or the data. We hooked the printer up to another computer that ran the same software and it still produced the wrong printed total.
We printed several other documents with no problem. We printed other statements (where the balance was not .00) and they worked fine. That led to another couple of hours down a dead-end rabbit hole.
Okay. So computers are good, software is good, data is good, printer is good (except for the extra dime). What is the problem? After two days of head scratching I finally decided to swap out the printer cable. The discrepant dime disappeared.
I have no idea how a bad parallel cable between the PC and the dot matrix printer could cause such and issue.

I once had a VCR where I did something like that. In my case I didn't want to spend the ammo, so I used a sledge hammer. Very satisfying, even though I had to sweep the entire garage.

I've had good results with Brother colour laser printers. The previous one lasted about 8-10 years (can't remember exactly), and this one has lasted 2 years, and is still going strong.
(I hope I haven't jinxed it, now  )

Agreed. I have a B&W Brother laser printer, and it just keeps working. And no fussing with ink cartridges, for the amount that I print a single toner cartridge can last a few years without having to worry that the ink will dry up...

Just an aside - I’m an old-ish fart (~60 y/o) and have been making a conscious effort to reduce or eliminate printing whenever possible. Never really been the tree hugger type but I am fairly frugal and prefer a clean desk. At first, every time I thought about printing something I’d gave it some serious thought… 80% of the time I’d end up not printing and going a different route. Now its a much lower percentage because I almost never think about printing.
I’m not trying to talk anyone out of printing or implying that you don’t need to. Certainly not virtue signaling. Just waxing nostalgic I guess. Again “old fart”…

What could be wrong? I swapped USB ports on the PC...nothing...not even a ding...
OK, that's a clue! Even though the other end of the USB cable was plugged in, it was plugged into the RJ-45 jack on the printer!
