Completely new to this and don't even know where to start.
Specifically, the problem is to programmatically add a picture(JPEG) as a footnote when printing PDF/DOC/DOCX files on Windows/Mac.
Most people use MS Word(on both Windows and Mac)/Preview(on Mac)/Chrome(on both)/Adobe Acrobat Reader(on Windows) to issue the printing job, so is there any open source add-ons for those softwares for this job? I am hoping that there is one for Chrome.
Or I will have to develop a printing application for PDF, DOC and DOCX. Any suggestions for which language to use?(I don't need a fancy GUI).
