It'll be better to check if the locations service is on for specific apps unnecessarily. It not only consumes data but also drains the battery faster. You can turn off the location service at system level for all the apps and turn on only when needed. However when it's turned on, it'll be enabled for all the apps that have location services on which will in turn consume data and battery. 

It's a better idea to turn this off for each of the apps and enable only as needed. You can see this setting for each app at settings -> Privacy -> Location Services.

Surprisingly notes could retain all the formatting from the Facebook post as is and came out good in the print out. Once the wireless printer is set up in your phone, you would want to do all the print out only from phone. Hence It’ll be helpful to include print option as default in all the apps.
