The OP in the linked post is a crazy weirdo. These are the sorts of insane posts you can easily find on any company's support website if they have a forum. I remember seeing one post on the Logitech forum where a similarly insane poster claimed that their F710 wireless controller was a "Microsoft scam".
A few posters recommend avoiding "HP's bullcrap" by using an Epson. Thankfully, there are crazies on the other side of that fence saying
Don't buy inkjet printers from Epson.
Just to condense down how insane the OP of the HP thread is into one concise quote:
I have re-staticed electrified my magnetic stripe
It's mostly a number of complaints about HP printers being a scam and how it refuses to allow any refilled or non-HP cartridge to be used. And yet other posters in the thread pop their head in about how they want to know how these people enabled that feature since they've been trying to prevent their company Printers from using refilled cartridges.
The "Printer bricks itself" thing is a result of many Inkjet printers having internal circuitry that tracks how many prints various components are present for. The idea is that the value would get reset when a part is replaced for that component and it tells you when you need to replace it. For some reason, some manufacturers have decided that the printer should no longer function once one of those values trips. This is sort of like if a Hard Drive manufacturer decided their drive would just refuse all ATA commands once it goes beyond the S.M.A.R.T thresholds.
I have an old Inkjet (Lexmark) from 13 years ago or thereabouts. It still works but it's a massive pain to deal with as it always wants to print alignment pages, then the color cartridge doesn't work at all but the printer pretends it is.
I bought a Color Laser Printer in Feb 2015 and haven't looked back. Toner lasts longer, doesn't dry out, and oddly it's cheaper than ink.
There are of course the good old Laser Printer yellow dot-codes that people worry about.
