I recently was in Cuba and also visited a local print shop.
It was a delight to see dozens of hacked HP printers with tubes directly going into containers of ink doing all the printing.
The printers had small custom circuit boards attached and were mostly dismantled up to the very core of the machine. As far as I could see it all worked very well and print quality was also good at a low price (even for local standards).
HP doesn’t stand a chance against humans who are determined to solve a problem.
