[Koha] Print overdue notices for patrons without email address

We are operating Koha version 3.04.01.000, and I've been unable to figure out how to send paper overdue notices to our patrons who do not have an email address. Email notifications go out fine, but all the notices for patrons who do not have email go in digest form to our administrator account. As part of the release notes, I did see that "Print overdue and hold notices for patrons without email addresses" should be supported in 3.04 - can anyone point me to documentation on how to do this, or share with me how you set this up? Thank you, Nissa Flanagan Systems/Technical Services Librarian Merrill Memorial Library Yarmouth, ME 04096 (207) 846-4763
