What printers work best with Planning Center Check-Ins for a mixed Windows and iPad setup, and how do I fix frequent printer connectivity issues?

Answer

Brother QL-820NWB recommended for mixed Windows/iPad setups; use USB for Windows desktops and Bluetooth or Wi-Fi for iPads; fix flakiness by disabling sleep mode, template mode, ensuring 2.4GHz Wi-Fi, and keeping the Check-Ins app updated to 3.0+.
