The label wizard allows the creation and printing of labels in the user environment. To print formatted fields, however, a form with the appropriate formatted fields must be used.
Create a form and place the appropriate formatted fields on the form, as you would like the fields to appear on a label. Then using the label wizard, you would need to pick this form to use for printing. This can be found on the lower left hand side of the label wizard labeled "Form to use".
By choosing a form in the label wizard, 4th Dimension will print the labels according to the design of the specific form. As with any print job, 4th Dimension executes any form or object methods associated with the form.
