Previously on the Nokia N8, there was an option that allowed the user to print the pictures, this option was available when the Nokia N8 is connected to a printer. Users have asked Nokia at the Discussions forum and the response received was that the printing option is no more available with Symbian Belle.
The Nokia Moderator that responded mentions that it will be taken into consideration for future updates. To some it would not make sense that this feature has removed due to the reason being is that a new update should always bring more features and not less. I tried searching for an application on the Nokia Store that allows the user to print pictures but found nothing.
There is always an option to degrade your Nokia N8 to Symbian Anna, follow our guide here.
