A. 1. Check print settings: Ensure that the print settings in the app are set correctly. Go to the print options and make sure the paper size and type match your printer's specifications. 2. Adjust photo dimensions: Before printing, crop or resize the photos to fit the printer's paper size to avoid white bars. 3. Use a different printer: If possible, try printing from a different printer to see if the issue persists.

B. 4. Update printer drivers: If you're printing from a computer, ensure that the printer drivers are up to date.
