For this case, computing back:

94M printers are sold per year.

HP’s market cap is $29 billion.

So, fine them $1000 per printer they sold that has any sort of anti-third-party ink mechanism, payable direct to consumer. (This seems about right to me. It’s less than 10x the retail price of a printer.)

Production of a receipt or a picture of an HP branded printer serial number should be all that is required to obtain the $1000. If they fail to pay in 30 days, individuals can use the mechanism where the sherrif walks into an HP office and takes $1000 worth of stuff on behalf of the claimant.

After 12 months, any unclaimed money gets sent to charity.

As appropriate as that would be, I’d rather see the CEO and execs that approved this stuff go to federal maximum security prison for life than for all the unrelated HP employees to lose their jobs. (Though, arguably, their services would be better used elsewhere.)
