Default [Q] PDF printer/converter with "multiple pages per page" option

Hello everyone!

I'm looking for an Android app that converts/prints documents (.doc, .ppt, even other PDF) to PDF, but with a twist: I need it to be able to put multiple pages on a single page.

My user case is the following: I have a PPT converted to PDF, where each page of the PDF is a single slide. However, I want to make it a PDF with 2 slides per A4 page, right there on my tablet (I do know how to do it on the PC). Note that I already have apps that print to PDF, page per page! What I still couldn't find is one that has the option to put multiple pages on a single page!

Is there an android app that can do this?
