For transporting documents intended for print, or intended to look like standard size printed paper, off does a good job, and there's a reason for that.
For those unfamiliar with the history, Postscript is a popular language for computers to talk to printers. Windows, Mac and other computers could all speak Postscript. "Print preview" functions could also read the postscript commands to display a print-like view on screen. So if you wanted a platform independent document, you could just use those Postscript printer commands, zipped for smaller size. That's essentially what PDF is - a dump from a printer cable, zipped. There's no need for "select top tray" and similar printer commands that don't show on screen, so those aren't valid in pdf.
So yeah, pdf is good for printing because that's what the language was originally designed for.
* The above is of course a summary. Pedants can of course point out various changes from postscript to pdf.
