muttprint should honour the PAPERSIZE environment variable directly or indirectly by using `paperconf`.
Hi, Attaching a simple patch to fix this.
[Maximiliano Curia 2013-08-15] I am not competent to evaluate the patch, and believe it is better handled upstream. Did you try to forward it upstream? I did notice this strange part, though: Is the correct value really 'latter' with an 'a'?
Most likely a typo, I'm pretty sure I've only used it with A4. But it's been quite a while since I last used mutt and muttprint.
