If you have two pdfs and you want to print them in a single page, you can start by merging both in a single page in a 3rd pdf.
Maybe you need to install using the following:
sudo apt install texlive-extra-utils
Then you can merge using one of the following commands:
- Vertical
pdfjam *.pdf --nup 1x2 --outfile merged.pdf
- Horizontal
pdfjam *.pdf --nup 2x1 --outfile merged.pdf
- Landscape
pdfjam *.pdf --nup 2x1 --landscape --outfile merged.pdf
Happy hacking!!!
