We often use the overdue slip for testing changes to overdue notices. What if we had an option for all the notices, probably tied into the debug permission from 39142 to print a test of the notice without running the associated script. For example, on a patron with recent autorenewals, we could run the autorenewal email as a printable slip to see how changes would look with live data. For each notice we'd need to define which information it needed to pull for the patron, but it would make testing and previewing notices across the board much easier.
