WordPress.org vs. WordPress.comPrintFriendly button can be embedded on almost all types of websites including blogs created using WordPress. However, a common confusion is whether you're using WordPress.com or WordPress.org. Since we have two different kinds of instruction for different platforms, it's important to figure out what platform you're using.
If you're unsure whether yours is WordPress.com or WordPress.org, you can check for answer in the following ways.
Does Your Domain Have WordPress.com in it?Easiest way to figure out what platform you're in is to look at the domain. Does your URL/link/address of the blog/website end with "wordpress.com?"
If the answer is yes, then there is no doubt that you're running WordPress.com. Go to this page and click "WordPress.com" check box to reveal the instruction on how to add PrintFriendly button on your blog.
Does Your Blog Allow Plugins?However, all WordPress.com sites don't end with wordpress.com in the domain because the site allows Custom Domain Upgrade which removes the wordpress.com suffix at the end. So, if you're paying for your domain, you can't still be sure whether it's wordpress.com or wordpress.org. To figure this out, log in to your dashboard.
Now, look for a menu called "Plugins" on the left side menubar. If it's there, like the screenshot below, you are running WordPress.org.
Do you see the Plugins menu in your WordPress Dashboard? If yes, you should check out this article and follow the steps to install PrintFriendly button on your blog.
Simply, if the Plugins menu is not there, you are on wordpress.com and you should go to this page, click WordPress.com and follow the instructions.
