This was just a quick overview and it’s unlikely you’ll know everything about Print My Blog Pro by just reading this. There’s a lot more to be said about customizing designs and even creating your own designs, but this is a good start.
Play around with it and get familiar with it. The free version can create the PDFs just the same as a paid version, they just have a watermark. So you can try basically everything before paying.
If you still have questions, the best way to get support is to use the plugin’s built-in help page. You’ll find it on any WordPress admin dashboard page, under “Print My Blog”. In addition to send the plugin author an email, it will send a bunch of helpful debugging information.
And even if you don’t have any problems, it’s actually helpful for the plugin author to see what you’re making with PMB Pro.
Best wishes making great documents with PMB Pro!
