Adding a printable form to a page

You will need to create a special print stylesheet…

I am so new to coding, the style sheets is a little daunting – Maybe could you suggest a form plugin that could do this for me?

You try to add this on the end of your style.css

@media print {
  #header, .share, #sidebar, #footer, .entry-meta
  {
    display: none  !important;
  }
}
