printer friendly page or print CSS....?

Question

Is it better to make separate printer friendly page with "Click to print button" on main page or only print CSS is enough for accessibility and usability point of view?

Answer 1

I'd only ever consider print css, duplicating the page content doesn't make sense. The user is able to print preview, but they likely don't care that it doesn't look identical, they just want it to look good when printed.

Most users will just click print anyway - I've seen plenty of emails printed from Gmail where the whole interface is there - they didn't click the print friendly link in the application.
