In this release of Pro Blogger we include a new feature for Blog Posts called 'Post Printer'
This app block adds a clickable printer icon that can be customised by size, color and text.

Example Printer Button
Clicking the icon will output a clean whitespace reduced version of the post content for printing.
This means - no site headers, footers overlays etc cluttering the print and leading to excessive paper wastage.
Please see the KB article for further details
