0Adding a print icon to print individual blog posts

In addi­tion to this blog I also have a blog about recipes.  I decided that I wanted a print icon on the main page for each post so that people can print the recipes.  Googling provided vari­ous sug­ges­tions, none of which worked.  How­ever, I even­tu­ally cobbled togeth­er the fol­low­ing, which seems to work…
Edit the code of your blog and find the code

<!-- email post links -->

Above that put the following…

[javascript]<script>
func­tion printPost(postUrl)
{

}
if(opener.doPrint == true)
{
window.print();
window.onfocus = func­tion() { window.close(); }
}
</script>

<a expr:href=’"javascript:printPost(" + """ + data:post.url + """ + ");"’><img src=‘https://siteresources.worldbank.org/images/Print_plain.gif’/></a>[/javascript]

And you’re done!
