We’ve got a HP Deskjet 4100 and the instant ink subscription.
It works from the PC, from phones, from laptops, it never throws a strop about running out of ink, it just works.
I was late and in a hurry this morning and managed to print a returns label for something from my phone as i was looking for my keys, and it worked! That would have taken several hours with the old Epson ?
I’m usually pretty anti-subscription business models but this one gets a big thumbs up after all the hours/days/weeks of my life I must have wasted over the years trying to get the printer to work with whatever it’s (apparently not) connected to and accept the 50p cheaper off-brand cartridge.
