How can I print text messages from an iphone 5s?

I will be needing these texts to present a court case. The defendant admits multiple times to having my GF’s stolen property, and makes threats if she tries to get it / says she can’t get it because its in her house, etc etc.

There are many pages of threats and malice, including how she destroyed certain cherished objects. Serious threats and accusations were made as well that may be needed to defend someone else. At least 20 pages of dialogue probably need to be printed— I think the judge, human services and adult protective services need a hard copy of these threats.
