How do i print off text messages from my LG L38C ?

I don't know if your phone support it, but you need Cloud Print from the PlayStore. And you also need Google Document, also from PlayStore. Long press the text that you want to print, tap Copy Text. Now open the Google Document and paste it. Tap the 3 dots on the upper right corner, tap Share and Export, from here choose Print. Make sure that your phone is already set up with your printer.

You can email them, then print.
I held my finger on the message for a few seconds and it asked what I want to do - I selected forward and emailed them to myself.
One at a time...
