HP Printer Pop-ups

I'm not sure if this is the correct section, but this is a problem that has been bugging me for days now.
I have a HP Photosmart 5510 Series, and this hasn't been a problem up until a few days ago. I get this Pop-up, asking me to 'Align' my printer? And I honestly get 4 of them at once, maybe every 5 minutes. When I get home from school my screen is full of them, and it literally takes 20 minutes to clear.
I'm running the latest version of Mac, and I'm not too good with technology, but I'm not terrible. I have deleted everything to do with HP on my laptop, but still I get these pop-ups.

Someone PLEASE help me! AHHH it's driving me crazy!

Example: (I get 4 of these at a time...)

It's because of your new ink cartridge that you put in.

There should be a button that says "align" or "align cartridge" push that, and your printer will print off a special copy that basically tests to make sure that the ink cartridge is working properly.

Did a quick google search for your specific printer. HP has instructions on how to fix the problem: http://h10025.www1.hp.com/ewfrf/wc/...00657/loc:8&cc=in&dlc=en&lc=en&product=311255
