linux: printing pdf in booklet format

I have a 44 pages PDF. I like trees. I want to save money.

So I want to print a booklet (page 1 and 44 on paper 1 side A, page 2 and 43 on paper 1 side B, etc.) from Ubuntu. I can't find the right way to accomplish this from Document Viewer (Evince?).

sudo apt-get install psutils

pdftops -nocrop -paper A4 -expand origin.pdf test.ps

psbook test.ps test-book.ps

psnup -2 test-book.ps test-book2.ps

We use the last command to put 2-pages together.
Note:  /etc/papersize is consulted, so it is better to set a different page size, using psnup -pa4
