Yes, this is by design. The app's settings are application-specific.
Diagnosis: When you change print settings in the Brother Print Support App, the changes apply only to documents printed from that specific application. Switching to a different app (like going from Word to Chrome) resets to that app's last used settings.
Fix: There is no global setting. You must configure the desired settings (paper size, orientation, 2-sided, etc.) within the Print Settings window for each application you use.
Procedure: In any application:
- Select print command.
- Select your printer, click properties/preferences.
- Configure settings in the Brother Print Support App window.
- Click OK, then Print. These settings are saved for this app only.
