No print option on Child Safe browser on Iphone 6

I installed the Child Safe browser on my son's iphone 6 recently.  However, there is no print button on the browser, so he can't print his schoolwork to our wireless printer.  Other apps on the iphonecan see the printer and print to it, so this is not an issue with the network.  What do I do to allow him to print from the Child Safe browser?
