Hello Roger,

Here are a couple scenarios that may cover the situations that we talked about in today's meetings with regard to slim clients wanting to print with references to high resolution images not available on the client that was submitting the print job.

The ColorWave file referred to in the first Scenario is a document that contains proxies for the high resolution FlashPix images as well as vector art  and text elements.

           7.0 Declared Internet Resources

Scenario #7.1

A photography buff using an Internet Appliance wants to print a high resolution graphic consisting of a collage of photographic images and vector clipart at a service bureau on a dye sublimation printer.  His Internet Appliance does not have enough RAM to collage the images and clipart at a high resolution, nor does he have a fast enough Internet uplink to transfer a 300dpi 24bit color composite of 24MB (he is using a cable modem with slow uplink capability).  The individual photographic images were originally scanned into multi-resolution Flashpix format by his photo retailer and hosted on the retailers' web site.  
The graphic composition was created on the Internet Appliance with a ColorWave compatible application supporting low resolution image proxies pulled from Internet hosted Flashpix files.  
The End User connects to a local print shop through the Web and submits compact ColorWave print job (approx 20K) with Declared Internet Resources specified (url's pointing to the original Flashpix images).  Server at local print shop receives ColorWave job and then resolves and caches Declared Internet Resources before passing the print request to ColorWave Rip.  Rip is then able to quickly render a high resolution graphic composition from cached Resources. 
Note that the server knew only to cache Declared Internet Resources and needed no knowledge of their content or intended use.  If the server was unable to resolve any Declared Internet Resources, the print job would have been canceled (and an error returned to End User) and never forwarded to the Rip.

Scenario #7.2

A large Quark Express document is submitted for printing with a list of Declared Internet Resources.  In this case, we are assuming that Postscript has been modified to use higher resolution bitmaps in place of proxies used by Quark and to recognize url identified fonts.  
The server caches the Declared Internet Resources and then passes the job to a Postscript Rip.  
Note that here, the size of the transmitted Quark file will only be a fraction of what it would have been had it included the high resolution image files and all the fonts necessary for print -- thus the overall transfer time is significantly reduced.  Further, the spool space on the server is reduced as Declared Internet Resources would only be cached prior to printing -- not sitting in the queue from the initial time of submission until queue purge.
