Re: Motherf***ers. I strongly doubt this is the only HP that has done this.
You are right about the price of a cheap new printer vs. cartridges. So when my laser printer's cartridges ran out, it did the calculation and bought a new printer. Sent an email to everyone in the office that there was a perfectly fine printer with empty cartridges up for grabs.
One department called me about 10 seconds later. Their printer was broken. There was zero budget for a replacement printer. There was unlimited budget for office supplies like printer cartridges. So they didn't care that the cartridges were more expensive than a new printer.
