About ten years ago I discovered that I couldn’t use more than one HP product on my computer at a time. I had an HP printer and I’d bought an HP scanner. But the driver software couldn’t co-exist on the same computer. At least, HP declared they couldn’t, and they didn’t care.
They still don’t care about customers, except as a revenue stream. This is again clearly highlighted by their plan to send spam to newer HP printers (Computerworld). They’ve outfitted the new printers with Internet connections, presumably to provide automatic support and updates. They’re also planning to use the link to automatically print advertisements on these printers.
