I think my HP printer had that worm pre-installed.

We dusted off an old, wired, B&W low res Cannon laser printer last year. It's our utility printer for internal docs or stuff you'd prefer to review on paper. It feels like an old reliable car. I think we're still using the same toner from last year's rebirth.

I bet there are a ton of these old printers sitting in corners shadowed by some glitzy full color, wifi, Internet enabled new hotness printer. It's probably a smart move to grab one of these old workhorses off Craigslist if you just need to print plain docs.

Even better surely is to just tell the printer to report the toner as empty after say 30% use (like manufacturers do with inkjet carts!). Then when the customer sends the toner cart in you can recycle the toner (or just top it up and reset the cart or whatever) and sell it back to the customer ... instant sales increase.

Of course after a little while the customers going to notice a problem. So then you can sell them a fix (patched firmware) or a new printer. Play it right and you get to run the same scam again then ...
