[STR New]

If an A4 PDF document is printed with number-up=2 onto a US Letter page,
there is wasted space at the sides which it is possible to reduce.

This is because the A4 PDF document is first converted to PostScript in US
Letter size (with pdftops or ghostscript), widening each page in the
document.

If the document were converted to PostScript using the document's native
page size (A4 in this case), it would be possible to lay out the
document's pages at a slightly larger scale in the resulting output.

In other words, rather than increasing the width of each document page to
match US Letter aspect ratio, it would be better to increase the height of
each document page as it is laid out in the output.
