[pdftex] Paper format - PDF

[Jan Öhman]

Hello!
(I don't know where to find examples and manuals)...

How can I:
- Change the orientation of the paper (from A4 portrait to landscape).
- Control the margins (I want a printable area to 10mm from the edges).
- Incorporate a "print date" or "change/create date" in the document
- Selecting the font? - What name should be listed?
(Is it the filename on the font file or the font name in Windows?)
- Give the font an color

Is it possible?
