问题
I am trying to create Java program, which can read multiple pdf files and merge them into a single pdf file. Then print the PDF but while printing i need to merge multiple pdf pages in a single page and print. Even if it is a new pdf created, that is fine for me. I need some open source java pdf manipulation library to handle this. I know one solution is while printing, select multiple printing option for muliple pages to one sheet. But the printer i can access doesn't have such capabilities. Can anybody suggest some solution for this or is it possible in any other programming language?

You can use Itext pdf library to get this job done.
