I just replaced an old PIXMA MX472 printer and it uses the 241XL color ink and 240XL black ink and replaced it with a PIXMA TR4720 printer. The new one uses the 276XL color ink and 275XL black ink. I have several of these left over so I'm wondering if I can use the old cartridges in the new printer. They look almost exactly the same, just different numbers. Thank you!
