The difference between your monitor and printer are because the color schemes for each are very different. Your monitor uses RGB light (Red, Green, Blue), where as your printer uses CMYK inks (Cyan, Magenta, Yellow, and Black). Your printed piece will come out darker because a] if a color created on your screen is something a printer can't produce, it will go to a color that it can that is in the ball park of what it can create and b] your monitor uses colored light beams to create the different colors so there's millions if not billions of colors it can create whereas with your printer, it uses inks and therefore it'll be darker however slightly because of not using light. If you have the option, I'm not familiar with Adobe Elements, but I know with their other programs, you can switch the color scheme from RGB to CMYK. If you can
do it, I'd recommend you do it after you've finished doing whatever you do to your photos, right before you print them. Usually when you switch to CMYK the choices in manipulation, whatever it may be, can be very limited, so it's good to save that switch until the end.
As far as the drastic difference between colors with the different cartridges, to try and color manage your cartridges, there should be an ability within your printer set-up/preferences or program that printers often come with. They usually have some kind of color management choice. Whenever you get new cartridges or if colors aren't lining up, whichever, they have options to help realign your cartridges and do color testing.
I hope this helps!
