    Very nice. An overlap or page margin would be nice, to accommodate non-printable page borders, but pdfposter doesn't seem to support this without hacking (maybe you can hack it with a fake page size...). My solution to this problem was to print the output PDF slightly scaled down. But then you still have to cut it very precisely.

  • There is a patch adding --overlap-percent option here: gitlab.com/pdftools/pdfposter/-/issues/1

GUI solution

If the dimension (A4 instead of A3) is not important (as this is not important for viewing the file and can be easily adjusted while printing), you can use PDFsam (open source) which allows to rotate pages.

mutool poster -x 2 input.pdf output.pdf

Installation in Debian 10/Buster:

apt install mupdf-tools

For reordering the pages after splitting, you can use pdftk.
