I live in the USA.
I have promoted, installed and used OpenOffice and LibreOffice for many years.
But one thing has beaten me, the program always setups up to A4 paper size and I have never been able to change it. I am in the habit now, of whenever I create a new document (of any type) I simply format the page to Letter.
I am from the UK, and have used and like A4, but I cannot buy it here, and I don’t think the printer would take it even if I could!
Thanks for any suggestions or answers.
