I want to create an application on a Mac to convert multiple files (txt, pdf, doc, html, etc) to a single pdf file that can be printed. The real point is that if you have 50 texts you don't have to open every single file and click command-p.
I'm not quite sure whether the best way to do this is by creating a full-fledged app or an automator plugin (or something else). If I remember correctly there's a filter in mac os's terminal that can convert files to pdf (but I forgot what it's called).
So would an automator plugin do this well, or shall I make an app for this? Can you provide me advantages for each answer?
I've done cocoa touch programming before so I can write objective-c quite well.
