I noticed the same thing on my HP printers. Seems like I was buying ink all the time. I changed to a Canon inkjet and the ink lasts much much longer. I have been printing for weeks now with the pop up that my ink level is low. When it runs out it won't print at all. That's when I put in new. You can take the cartridge out and give it a good shake. That use to work with my HP for longer printing.
