Do I have to print all pages for Form 709?

Hello,

 

Unfortunately we cannot e-file Form 709, the gift tax form.  A bit of a silly logistics question, but do I have to print all 5 pages of the form if the last 2 are essentially blank?  I would like to print only the first 3 so that I can mail the form in an envelope with a stamp.  At 5 pages a sensitive USPS scale may send it back for insufficient postage and that is a headache I wouldn't want to deal with.  I've searched the IRS website and can't find a definitive answer to this question.  

 

Thanks!
