How can I print a PDF document on multiple pages?

This should do the job: command line PDF poster printer

To install, use apt-get as follows:

sudo apt-get install pdfposter

Example of usage for A4 -> A2 size:

$ pdfposter -v -mA4 -pA2 input_A4.pdf output_4_A4.pdf
---- processing page 1 -----
Deciding for 2 column and 2 row of portrait pages.

You can try Razor

1. First Print your PDF to File ( As Image , as png or jpeg )
2. Then use this tool to print it over to as many pages as you wish

This technique is called Image OR Document Stitching.
