This is a most excellent place for technology news and articles.
I have an HP laser printer from like 1992, before they turned to US=Privateers; rest-of-the-world=criminal pirates. HP died as a company when they spun off Agilent/Keysight as test equipment and continued the branding for contract manufactured consumer garbage. HP does not make anything. They market, place stickers on what others manufacture, and create ponzi scheme-like extortion scams, as the shriveled shell of a dying husk disconnected completely from their now long irrelevant past.
They died when inkjet ink became their core business the rest of the company revolved around.
Also Carly fiorina, she ruined it for women ceos for a while.
