I used a scanner a lot. But due to complications with usage, I can only receive them as one page PDF files. Most of the time, I want to print double sided, but that isn't possible when you have one page PDF files. So I use Docs to put all the files onto one page, then print that document with the double sided feature on. However, I have to convert all of them into PNG images because my computer wouldn't allow me to insert PDF files. Is it possible to insert PDF files into Docs like a PNG image? If yes, how do I do that?
