From the HP Smart app click the printer icon and then click on Tray and Paper.
If you cannot see such an option, click on Advanced Settings and then open the Settings tab, under Preferences click on Tray and Paper Management and make sure the correct Paper Size and Paper Type are set, as the used paper.
Click Apply to confirm the change and then close the HP Smart app for the settings to take a place.
Open HP Smart and select Print Photos, select your photo and then select Print.
On the print dialog tap the print preview and select Resize & Move, select Fill Page and click on Done, then on Print.
