    Well, if mobile devices cannot fetch large documents (to display
    them), then printing them is a bit useless, right? Better to just
    provide web-enabled applications for wireless devices to access
    when they need to handle large documents.

    The only operational scenario that I see where this would make *any*
    sense is when viewing a large PDF file that has been linearized
    ("optimized") for the web, and even then you cannot have a proxy
    between the client and server or none of the byte serving (which
    allows a light-weight client to view the PDF file in pieces) will
    work anyways.

    I have yet to be convinced that print-by-reference is anything other
    than a "gee wiz" feature.
