I am looking for a command line tool that "converts" a pdf file (whose size is larger than a4) into a single pdf file that consists of multiple a4 pages. The new pdf file, when printed, should look like the original content without scaling the original.
Searching the internet, I found
pdfposter. Yet, it seems to require the size of the input pdf file which I don't know.
So, is there a tool that does that.
