For Change Format (custom) printing, you must specify which fields to print.  Part of the selection indicates how to print the field.  Placing a single character at the start of each field to be printed is how it is done.  Put a 0 to 9 to specify the number of spaces to follow the field.  Put an S, D, or T for single, double, or triple line spacing following the field:
