If you are using the same font for each statement. You could do something like this in the place where you specify what to print

IIF(printwhen1,line1,"");IIF(printwhen2,line2,"");IIF(printwhen3,line3); etc...
The important thing is that the ";" will remove any empty line inthe expression. For example, if you want to display a multi line address with something empty line, you'de put this :

address1;address2;address3;city;postalcode; etc....

If you have different font however , I don't think I can be of any help
