Unable to Print from the Finder

The Print option (Command-P) is grayed out when I select several PDFs to print in a Finder tab. Since I print groups of PDF documents for clients multiple times a day, and I already posted yesterday under another topic about periodically losing the ability to navigate the Finder Browse view with the arrow keys (I use extensive folder structures), looks like I will be uninstalling this yet again.

A shame really, since it handles the tabbing WAY better than the stock Finder does.
