Are you talking about a literal print-out (like a word document or something), or a print-out in terms of displaying all contacts?

If it's the latter, you will want to add the Conctact Directory block to whatever page you want to display it on. Below is a link to the documentation on how to use it:

I believe there is also an option to export each directory from the dashboard as an excel spreadsheet (or at least a .CSV file which is compatible with Excel).

If you mean an actual print of the page there are several options available.

1. Create your own print styles and add to the header. That way you can control the layout of all pages and get a consistent print look throughout your site.

2. Install the add-on "Print My Page" which basically does the same as in #1 above, but from within concrete5. Print My Page has a dashboard page where you add your styles and you can then add a Print My Page block to the pages you want to apply the print styles to. Print My Page works on a global basis and sets the same print styles on all pages you add the print block.

3. Install the add-on "Page Printer" and add a Page Printer block to your page. When adding the block you need to supply the print styles for that page. Same principal as in #1 and #2 but on a per page basis so you can have different print styles for different pages.

No matter which way you want to go you need to take a look at the source for your page so you know what classes and ids you want to give different styling upon print.

Edit: Adding to growthcurve you can export each directory from the dashboard. Go to Dashboard and click on Manage Directories in the Contact Directory pane. Click Manage next to the directory you want to export and then click Export to get a .csv file with all contacts from the directory you are in.
