If you mean convert a form to a report and make it appear exactly as it looks on the screen then I don't believe this is possible, unless anyone else here knows differenltly. You can arrange the report to have a similar layout to the form upon designing it but nothing that I know of that will automatically take the layout of your form to a report.
You can print a form by placing a command button on your form and using the wizard, select print form and this will do what you require, however forms are not really meant for printing. Forms are meant for user interaction and displaying information while reports are your best option for printing.
