Print layout

# Feature Request

Also see #53. Now, 8 years later, next try ;)

Let's optimize print layout. Lazy loading of images shouldn't be a problem now.

Currently it looks like this:


Disadvantages
1. Much whitespace
2. Unneeded elements like breadcrumb or footer links
3. Admin Console button is shown
4. Content is hidden behind fixed header
5. hr-tag isn't shown in print layout
6. more

With minor modifications it looks like this:


When I provide a pull request, will you implement it?

Start by reviewing the existing print layout and the earlier issue #53, then compare the current and proposed screenshots. Check each listed disadvantage, including whitespace, hidden elements, fixed-header overlap, and missing horizontal rules; done means the print output matches the proposed layout. No file or test entry point is named in the issue.
