I've had HP computers 'forever'. I still keep Deskjet 970, 722 and 822s around because they do one thing no other color printer does - print on continuous-form paper - so I can have a 13-page or 28-page full color banner. It's great. But the 970 series, along with the Epson R200-300s (and therefore Canons) have all tricked users into auto-updates. This isn't a new strategy at all. However, by blocking their software via firewall settings, their software runs but fails to connect. No updates are applied.
The WORST thing these manufacturers are getting away with is refusing to supply drivers for new Windows versions. Printers that are perfectly great, hardware-wise, but Microsoft needs to 'sign' them for authentication.
Why don't the printer-makers let us mail THEIR products back to THEIR disposal units - like the CEO's backyard pool, for example? Let's fill up THEIR landfills with THEIR printers they choose not to support. The Landfill Issue should be getting far more publicity.
