No surprise there then
HP will do what HP does in these cases, paint itself into a corner.
They'll EOL supplies for more printers and make those very printers refuse to take 3rd party inks etc by applying software updates in the background and without the customer being able to say NO.
They've already tried this but IMHO, that was just dabbling their corporate and very putrid toes in the water.
The replacements will be so locked down that 3rd party companies even thinking of making inks/toners etc will be hit by mega, mega sized lawsuits.
That in turn will make customers think long and hard about buying anything from any company flogging HP branded kit.
Revenue will be down and we will see more of the same in a rinse and repeat operation.
