pdf, including ones at research site ssrn, in general have huge margin. when you wanna print 2 pages per sheet, the text become smaller with a lot of unnecessary white space for the margin
What do you need?
pdfcrop, which is available at ubuntu, but not centos7 afaik at the time of writing
How?
pdfcrop -h
pdfcrop <input.pdf> <output.pdf>
Appendix:
What if you don't have ubuntu?
if you have centos7 running on virtualbox with windows host, here's what I did:
- download ubuntu 18 desktop installation iso
- Virtualbox, existing vm, storage, optical drive
- select the downloaded iso
- check Live CD/DVD box
- start VM
- choose "Try ubuntu" after it boots from disc
- Follow https://askubuntu.com/questions/378558/unable-to-locate-package-while-trying-to-install-packages-with-apt to update package download source
- Open a terminal in ubuntu
- sudo apt-get install texlive-extra-utils
- pdfcrop <input.pdf> <output.pdf>
- ubuntu map windows host's shared drive
- netstat -nr to see window host's ip address from ubuntu
- ubuntu "Files" app, which has a folder icon
- connect to Server by entering smb://<windows ip>
- drag and drop <output.pdf> to shared folder
