Query: HP Plus cartridges are a waste of money and time

I print a lot of fairly large (13x19 paper) photography prints on my old HP Deskjet 1220 C printer. I was using the standard 78 cartridge, but recently changed to the 78 plus. I partly made this switch for the color, but mostly for the longer fade resistance. Unfortunately, only about 50% of the cartridges work correctly for me. The main problem is streaking and the fact I have to print a number of "sacrificial" prints before any look usable, and that's in those rare cases it prints OK. I just completed a number of "experiments" with two brand new cartridges, including heating them up in the sauna (because I thought maybe it was a temperature thing) and also just printing plain squares of various colors. My conclusion is that I am buying an Epson printer.
