To print the block you can use below code,
$addblock = module_invoke('addthis','block_view','addthis_block');
addthis = "module_name" = This is module name can be found in block configuration URL or the name of the module's folder
block_view = Type of view
addthis_block = "block_delta" = This can also be found in the block configuration URL
*Configuration URL = Open blocks page in Drupal 7 which is "admin/structure/blocks", and click on "configure".
