I highly doubt there would be any restitution for rendering the printers (we paid for) useless. Nothing beyond a weak "we're sorry about that" and maybe a 10% off coupon on their subscription plan.
Sad state of affairs when this is all we expect out of these monolithic mega-corporations. Totally lost touch with the consumer.
PS - what they *should* be doing asap - is pushing out the previous version to every single printer that got the new version. Don't they test these firmware updates in-house before sending them to the public?
