How to I download HP Photosmart 5510 printer software when the software i've been given isn't compatible with Lion?

I have a Macbook Pro which i bought in the last week with Mac OX Lion already installed.

I also bought a printer from apple called HP Photosmart5510.

I've been able to print, as it is a wireless so i have done so through sending the document over the internet. I can also "scan to print" using only my printer, However i want to be able to scan documents on my printer through to my macbook.

THe printer also came with a CD with the installer, but whenever i click on it it says that the software isn't compatible with Lion.

Has anyone else had this problem and could possibly help me??

Thank you!
