I don’t read every IETF RFC but I try look over a lot of them in my RSS reader as they are published. The IETF RFCs are all paginated like this, which is annoying.

RFC 6691 TCP Options and MSS July 2012
While this might have a been a good idea twenty years ago, I feel confident that most people do not print RFCs.
And when they do, I’ll bet a lot of people are using ISO Standard A4 which makes printing even less likely. The RFCs are formatted for “US Letter” using plain text so you can’t print them even if you wanted to.
I imagine its simply that no has taken the time to fix it but it’s also one of the little things that annoys the international community that the American perspectives dominate Internet standards. Being more inclusive and respectful of others would help to solve some of this problem.
