Hi Mark Alexander, I am not sure of using Koha for generating printed letters, but we developed our own method for handling overdue issues.
In our college environment, even though emails are sent as a part of overdue notifications, only few students will have the habit of checking emails and respond accordingly. But some portion of students won't check their emails or submit non-working email ids, and will not respond to the library. To overcome this problem, I have complied separate Library Dues Management System using PHP and MySQL. This system can be accessed within the campus by all the other departments, namely, Library, Respective Departments, Admission Section, Head of the Institution, Head of the Department, with only VIEW Options (No data can be modified) and can be accessed via Login and Password. This helps respective departments to follow up with over due issue at their convenience. Overdue list is prepared at the end of each semester with Koha Reporting , and same data is fed into this Library Dues Management System. (Because, administration department keeps asking details frequently, and koha library system access can not be shared, to balance this, I set up separate application) This system has printing letter option, which uses a pre-filled template (body of the letter), and inserts respective barcode, title, issue data, due date, etc. Once the letter is generated with auto -filling, it will be printed and only signature is collected by the Librarian and transferred to the postal dispatch section of the College. Two copies will be printed each time, one copy is kept as proof in the Library.
