Hi there and welcome
this you cannot doe via iClud, you need a separate software program for this
The best program for this is Phone view which you can get here
You install it and then connect your iPhone to the computer and it will download all the text messages plus any other content
You can then print and save these texts no different to printing anything from your computer
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
No, it only works for windows (sorry it said you had a mac here)
For the PC you use a program called Anytrans which you can get here
After downloading and installing AnyTrans on computer and install it, you can easily print iPhone texts/SMS now by following the 3 steps below.
Step 1. Run AnyTrans and connect iPhone to computer with USB cable > After AnyTrans recognizes you device, scroll down to click "Messages" category to view all messages.
