It's in demand. As mobile devices become more capable, users want the ability to print from them. Imagine an executive visiting a remote branch office and getting e-mailed a PDF of an important document to review. Which do you think he'd rather do: Ruin his eyes trying to read it on his 3-inch BlackBerry screen? Or send it to the nearest multifunction printer? Mobile devices are everywhere, and users increasingly expect to have the option to print when it's convenient.
