Before printing an order there must be an order form active in References. Go to the References ability, select Forms in the sidebar, and locate the Order Form.
Check the Form Active checkbox, and save the changes by going to the Edit menu and selecting Save Record, or use the Command-S keyboard shortcut.
Next, set this as the default order form. Within the Forms Preference, set the default Order Form to use when printing an order.
To print an order, select it from the Order Table, and go to the File menu and select Print, or use the Command-P keyboard shortcut. An information sheet will print for the current order.
