Back in 2009, Brent Johnson created a way to create multiple contacts per student.  The customization included a reporting engine report to create a PDF of Avery 5160 mailing labels.  I asked Brent if I could revise it to work with the PS 12 version of student contacts and he said yes.  I've uploaded the reporting engine report to this site and it can be found here.

The SQL for the report is based on a free sqlReport that can be found here
