Hi David_Gascon,
Thank you for your purchase.

Please read our blog post about translation and localization to get a clearer picture of situation. 

If you want just to translate mentioned buttons maybe it would be easiest to just hardcode translation in file 

../wp-content/plugins/wpdatatables/source/class.wpdatatable.php

around line 2016 you can find 

'text' => __('Print','wpdatatables')

just change 'Print' to appropriate text. Similarly you can find text for all other buttons in the code below.

If you want to be able to customize all strings from our plugin you can use approach from that blog post.


Best regards.
