OK; you ask a lot of questions here. Let’s take them one by one.
1) I would that the icon of the print appears near the social icons (I use Sassy Social Share) immediately after the last icon of Sassy plugin.
You are going to have to reach out to Sassy Social Share and see if they provide a filter or hook that allows you to add the shortcode to their social share element.
2) When I try to print the articles, at the top appear the title and the subtitle two time. I don’t want this.
The duplicate information is for screen-readers. You should either set the .screen-reader-text class as a do-not-print element, or simply add the following CSS to the print-only page:
.screen-reader-text {
display: none;
}
This is basic CSS and is not related to our plugin. If you need further help with your theme or CSS please reach out to your theme developer.
3) When I print the articles, display only the social icons Share and Like of Facebook, but not the others and there are a big space between these and the image. How can I solve this.
The social share icons are being generated using CSS. For example the Twitter Icon is defined using the classes:
heateorSssSharingSvg heateorSssTwitterSvg
and these classes are defined at:
https://www.homosum.it/wp-content/plugins/sassy-social-share/admin/css/sassy-social-share-svg.css?ver=3.2.18
Therefore this CSS file needs to be included on the print-page.
after the image, display the name of the site and the date in which the article has been load on the site.
At the moment, I would that this date don’t display. Is it possible?
Yes. But the element that holds the date needs to have a unique class or id assigned.
The things you requested require a bit of CSS and maybe some modifications to your child theme. While this is beyond the scope of supporting our free plugin, we do offer a very high level of personal support with Print-Pro-Matic that would cover such technical assistance.
