print text messages from iPhone

The easiest way to do it is going to be by getting an application such as PhoneView (Mac) or TouchCopy (Mac or Windows). Both will allow you to archive your messages as pdfs or text files, both of which are easy to print.

If you are doing this for some sort of legal issue, contact your attorney for advice before doing anything.

Take a Screenshot of Text Messages for Printing

Open the text message and then press the "Home" and "Sleep/Wake" bottoms at the same time. Then tap on the share button on the edit page of the screenshot and click on "print" to use AirPrint; or you can email to yourself and print it on the computer. But this method may not be suitable for long messages threads or bulk actions.

Send Texts as Email to Print

Open the messages thread that you want to print, and tap "Edit" to select all of the messages, then copy-paste them into an email. You can email it to yourself for printing, but you will lose all the date/time information.
