Apparently submits electronically sometimes - but if you need attached statements, for example for f1116, you have to print the product and mail it. Otherwise supports surprisingly MANY forms - many of them with some limitations which are enumerated for you. Some schedules are not included, for example this year f1116 requires 1116 Schedule B for carryovers and that's not provided here. So again if you need f1116 then you'll be printing and mailing that. Really... Many forms are included.
