I'm not sure there's anything we can do about this since every browser will print this differently.

We can create a simple print.css stylesheet which should work for all browsers equally, since print.css usually removes menu blocks, etc.

The print.css solution is working really well for the other sites. However, there's a pretty big issue with the community theme always displaying a very broken and outdated "Admin ussf" theme. This theme has not been maintained with css updates, yet it's the only theme most users will see.

I'm hoping that we can get rid of this theme all together and if need be tweak the working theme to fit civicrm fields, etc.

Then, the print.css sheet should be beautiful.

I've made dozens of changes to the print.css file, now it should print as one page!
