Add a print button on fillable pdf with javascript

Hi! 

Can someone help me with JavaScript for a print button on a fillable pdf please?  I am not a coder so I just need the script to add to the pdf. 

I created a form that can be opened from a website.  Once open, I have a buttons to email the form, reset the form and print the form.  The email and reset buttons work great, but the functionality to print it is not in Adobe Pro DC.  I have to add JavaScript in the properties.  I just need a simple code to open the print dialog box. 

Thank you in advance for your help!
