[cups-devel] Adding IPP-over-USB Support to CUPS

[Kennedy, Smith (Wireless Architect)]

Greetings,

IPP USB is an extension to the USB Print interface class definition (class 7) that was ratified by the USB-IF in December 2012. All USB-IF standard interface class definitions are listed on their "USB-IF Device Class Documents" page:

http://www.usb.org/developers/docs/devclass_docs/ <http://www.usb.org/developers/docs/devclass_docs/>

If you look under the "Printer Class" heading you will find "IPP Protocol 1.0 and Adopters Agreement". In that zip file you will find the final 1.0 revision of the IPP USB specification. As far as I can tell, this is available without authentication or a paywall.

I have removed the PWG hosted early draft white paper documents, as the final specification stripped away a number of things present in those early drafts, and they will be misleading.

Smith
