Printing for myself and designing some more general solution are two
completely different things :)

Various printers and drivers can go weird if size of file isn't matched
in paper in tray so you should provide both A4 and Letter. Of course
layout can be the same but files should be prepared separately.

Letter -> 216x279
A4     -> 210x297

A4 is narrower but higher. If you want the same layout you have to
create your own "format" which will fit on both papers.

Maybe there is fault and he wants 350dpi? This is becoming more popular
recently.
