> Knuth seems not to have considered paper size as something the TeX engine > needs to know about. This is the core problem. You **always** need to have to set a lot of parameters, see the geometry package documentation. None of the above commands does anything in this direction, so the default physical paper size is used, which is set via paperconf. What youare asking is a fix to testpage.tex, to use geometry or some other ways to set the *physical* page size. But that is as said not the basic assumption. You can use testpage, and then print it on the correct page size. > According to the TeX Live mailing-list, this is a Debian-specific > issue. paperconf is Debian specific, so the default physical page size setup is Debian specific (TeX defaults to letter). The testpage.tex itself is what it is.
