Submit is missing from the form elements list

' Submit' is not listed in my form elements. Why is this? How can I change the properties eg to print ?

The layout of the form on the screenshot you provided is 'Single Question in One Page'. The submit button field is removed from the list of Form Elements inside of this layout, but it will be added by default to the last page of the form. 

The print option is also available with this form layout. 

If you want to allow your users to print the form, you will have to change the layout of your form to 'All Questions in One Page'. This can be done on the Form Settings page. 

Feel free to contact us if you have any other questions.
