When I had the HP everyone said use pattern, as the ink was so bloody expensive, around 3-4 times the price of Lexy, so tried some patterns, never did work well, most wouldn't work at all, but genuine were always good, thought it was good quality until I got the lexmark, but that's defo better, like the double sided printing as well.
Think at least for now will stick with genuine, as good price, needed a bank loan to buy new hp ones!!
