Hello

Activate the debug mode

go to the menu Contacts -> Localization -> countries -> select countries and open the form view.

Under the "Advanced Address Formatting":

Modify the field "Layout in reports" and set your address format.

Set the value of field in one line like

%(street)s %(street2)s %(city)s %(state_code)s %(zip)s %(country_name)s. 

Save these changes and print reports.

I hope this will helps you.
