Select Quick Embedder from Settings of PDF Poster. You can change the quick pdf embedder settings from here.
First of all, embed any pdf without creating a post. To do that enter [pdf_embed url=’your_file_url’] shortcode and replace your_file_url with your pdf file URL.
Also, for the settings of the quick embedder, set width, height, enable/disable Allow Print, Default Browser, Protect Content, Alert Message, Toggle Menu, show/hide File Name, Download Button, View Fullscreen Button.
