I'm not clear on notices/slips. After reading through the documentation. I've looked through the notices/slips templates and also see there's email and print fields. I have rules/boxes ticked for the 1st, 2nd, 3rd in the intranet settings but I don't understand how to trigger the overdue document to be created so that it can be printed and mailed. The overdues area gives me the data but there's no "generate slips" or similar to get a paper copy.  I looked through the cronjobs thinking there was maybe a service that would do that nightly and I see two things that maybe had to do with my goal. It looks like it uses a python service to transform an html message (presumably the one set in the notices/slips settings area) and resave it as a pdf. But I do not understand where that would be saved to by default or how to set a path that would be accessible by librarians. I'm guessing one is probably supposed to set it to the same directory that is accessible via the intranet files area but I'm just guessing. My end goal is to make it easy for my librarians to print off all overdues monthly and mail them out, but I'd also like to better understand how the services that are running go get those overdues and what service does the thing of putting them into a printable pdf (or whatever). The documentation I'm reading doesn't have much information on that outside of how to get them email notices going.
