How to use A4 in Landscape mode?

[kittiu]

As in the question, I still not seeing this option. I am thinking the correct way is to use Page Size = CUSTOM, and define it by mm?

Even so, I think having landscape option that change the mm can be handy 👍

OK still got some other problem. I did try CUSTOM mode,

But when I print it, it looks like this. It was squeezed into portrait.

But luckily, the PDF download still OK

You need to set "custom print format" as default for doctypes.
