If you are photo printing thats where you might get let down with non-brand inks. I’ve some pictures of faces lit by red light in the dark. Cheap cartridges in my canon printer just couldn’t print them at all, just a black page with a brownish smudge on them, the red ink lacked the punch so I had to buy a set of genuine ones to print them. If you are just doing document printing and plain paper stuff non-brand stuff is broadly fine.
some don’t have the appropriate chip to say to the printer ‘yes I’m a *cough* original cartridge’,
I’ve an HP printer that is currently refusing to reckonise a genuine HP colour cartridge which is only about a 1/3rd used, its the extra large, extra expensive version as well. Annoyingly its the printer I mostly only use for draft black printing (its super fast and can knock out 100 page film scripts in few minutes whilst shaking the table from side to side) but it refuses to print in black, even when set to ‘black ink only’ if it doesn’t like the colour cartridge.
Its a bollocks isn’t it
