The only way currently available for a Facebook Page to post in Facebook groups is for the page and group to be linked by the admins.
in the screens shot below you can see my business/fanpage along with the “groups” tab. As the owner of the Adscience.Group, I’ve linked the page and group together.
When you visit the group and you want to post as your page you have to choose the correct profile in the pulldown menu.
Here, you see that when I click the small profile picture in the upper right of a new post, I have options available to choose who to post as. In the image, I can choose between my personal profile and my public figure page.
What you can’t do yet, is to post in a group that doesn’t belong to you as a page.
