Simply put, I'm tackling a massive project right now. While my print.css is functioning perfectly, the task of constantly previewing the print page has become incredibly frustrating.
What's more, it's impossible to inspect the page effectively as some elements appear completely different upon inspection. I've resorted to manually adjusting them and adding an extra 160 lines to my print.css file, but they stubbornly remain vertical instead of horizontal.
If only Chrome had an extension or some other tool that allowed me to easily inspect a print preview or simulate my browser to act as if it were in print mode, that would be a dream come true for me!
