I just sent an email to the info@ address. Please let me know what you think?

Best,

You are correct. The original language was this:

Consumer Photo Lab Digital Printers
There is a free database ICC printer profiles for digital labs worldwide at http://www.drycreekphoto.com. The printers covered include Fuji Frontier, Noritsu, Agfa D-Lab, LightJet, Durst and Chromira printers, among others. Because these printers do not recognize embedded profiles, it is necessary to convert your files to their profiles. Converting to these profiles will give you the best color fidelity and allow you to soft proof your digital files before committing them to print. Labs that don’t use profiles usually require that submitted files are converted to sRGB and saved without an embedded profile. Using the sRGB color space instead of a custom profile may yield less accurate color lacking the full gamut such printers can produce.

Unfortunately, other folks felt that this was a mistake. We do everything by consensus, which in this case resulted in incorrect information. This will corrected in the next version.

In our defense, we did get this web resource produced, and it is helping folks as we speak. If you really want to be part of the solution, John, how about if you communicate your other concerns to me or the the UPDIG group so we can make improvements.

Richard Anderson, UPDIG chair, principle author.

Consumer Photo Lab Digital Printers - Because these printers do not recognize embedded profiles, it is necessary to convert your files to their profiles, then save them with the profile embedded.

This goes directly opposite to Ethan’s recommendation here:
http://www.drycreekphoto.com/Frontier/using_printer_profiles.htm

Example color managed editing and printing workflow - #17 Do not embed the profile in the saved file. Frontier, Noritsu, and Agfa printers ignore embedded profiles, so you are only using up disk space. Additionally, many versions of the Fuji Frontier PIC driver crash when given files with profiles embedded. In the File→Save As dialog box, uncheck the “Icc Profile:” box in the Color settings area.

It is one of the indications of how DNG is addressing important aspects of digital photography that aren’t being addressed elsewhere:
