On the old server we had prince 7.1 with the associated license. I downloaded
prince-7.1-1.centos52.i386.rpm and I tried to install it but I receive the following error:

rpm -ivh prince-7.1-1.centos52.i386.rpm
error: Failed dependencies:

How do I handle this?

You can install the necessary libraries. Is your server running CentOS 5, or an equivalent distribution like RHEL 5?

It is running CENTOS 6.2

Prince 8.1 will have RPM packages for CentOS 6. If you need to run 7.1, using a static binary may work. I'll provide the link to that in the other forum thread.
