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. -- ______________________________________________________________________ Michael Sweet, Easy Software Products mike at easysw dot com Printing Software for UNIX http://www.easysw.com
