For the print button you could use code (the XDocument.PrintOut() method) in
the event handler for the button to print the active view (see
http://msdn.microsoft.com/library/en-us/ipsdk/html/xdmthPrintOut_HV01021397.asp?
frame=true).
Note that your form must be fully trusted to be able to use this method.

For the delete button, you could add 1 rule (with several actions) on the
button to clear all the fields. You must add 1 action for each field to be
cleared. Clearing a field would be equivalent to setting its value to
something like e.g. an empty string.
