Bug 16149 adds the ability to combine report results with a custom notice to generate emails. Many libraries do not reliably have email addresses for their patrons and could use a method to generate print notices. This could be a failover from email to print (as overdues do) or a separate cron.
Andrew, can you explain a bit more how bug 16149 should be extended for this? Also, if it's about the print notices, what would be the advantage over the normal notices print option?
