Tip for saving printing paper

One can save on paper supplies, by printing multiple pages in single A4 paper sheets.

On GNU/Linux you can do this with the pdfjam utilities.

# apt-get install pdfjam

The following cmdline turns file[1-3].pdf into a single pdf file

$ pdfjoin --outfile single.pdf file1.pdf file2.pdf file3.pdf

We now put two pages into one (in landscape mode)

$ pdfnup --outfile 2_pages_in_one.pdf single.pdf

You may wish to enable double sided printing through CUPS at this point.

Your job is now ready for printing.

$ lp -d printer_name 2_pages_in_one.pdf
