Issues when I print my dashboard

I have the following issues when I print my dashboard:

  1. The colour scheme of the widget headings is lost when I print and they revert to black text on white background.
  2. The dashboard doesn't fit on the page width when I print even though I select scaled to fit page on the printer settings.
  3. How can I remove the header and footer from the print?

I have attached a pdf of the print and a screenshot of the dashboard display in Smartsheet for comparison.
