[IPP] PDF Raster and IPP Scan

By quick skim, PDF/Raster appears to be the raster capability the exists within PDF, with some additional restrictions. Not quite sure why it requires a separate specification, except for  the comment that it is the file format required by “TWAIN Working Group’s new TWAIN Direct specification -- the first zero-footprint, cloud-based version of its royalty free open standard protocol that allows applications to talk directly to document scanners without the need for vendor specific drivers.” That us the rub and would suggest that IPP Everwhere/Scan  would have some very serious competition, if we ever formalized it. The scanner industry has a long history using TWAIN and, as in other areas, it will tend to continue with what is familiar. Still, a common imaging protocol for MFDs may find some support.

The IPP Scan Service spec appears to require that Scan Services support PDF.  Modifying that to allow lower end devices to support a PDF subset not be a major effort and might have some benefit in showing some degree of universality. Is there any product that uses IPP Scan?

Thanks, Bill Wagner

Just playing devil's advocate here. What does PDF/raster provide that the existing formats do not? Why did a new subset format need to be defined?

I saw this announcement this morning.

Should we consider adding support for this format in IPP Scan?
