HP pays out in another settlement over ink cartridge DRM

 HP agreed to pay up to $1.35 million in compensation to users

in four European nations for its implementation of ink cartridge DRM in 2016.

In a recent settlement with the consumer organisation Euroconsumers,

 HP previously consented to such payments to clients on other continents.

The issue began when some HP printers' firmware was updated,

causing them to reject ink cartridges from brands other than HP,

which could be recognised by the absence of HP's DRM chips. 

DRM may also detect refilling of a discarded HP cartridge. Third-party ink is typically less expensive

 than "official" cartridges from printer manufacturers who follow a razor-and-blade 

 business strategy to recover costs through the sale of inexpensive machines.
