Comment 6 for bug 1704873

Currently testing and merging code from 1685929 with the stuff in user/berick/lp1704873-webstaf-print-label-review ...

I'll likely push an integration branch since on 1685929 felt it was best to extract and DRY up the itemSvc service from item/app.js into it's own separate service "egItem" that lives in staff/circ/services/item.js
That code is in user/cesardv/lp1685929_checkin_actions_itemSvc
