user access

I am using confluence to provide a customer portal to selected documents.  Customers are not allowed to edit these documents or the parent pages of these documents (view permissions only).  I've just noticed that the menu option to export to PDF is gone now.  I'm not sure when the option fell off the menu.  It may not have been these page restrictions at all.  I have confirmed that the customer's user group is set up with Export permission.

Any assistance that does not include 'user must edit to be able to print' is VERY welcome!  :-)
