Hi Ira,
If we remove the 1284 device ID requirements from IPP Everywhere 1.1 and subsequently an IPP Everywhere 1.1 conforming client queries an IPP Everywhere 1.0 conforming device, which returns a 1284 device ID, should the client just ignore the 1284 device ID response?
Thanks.
Best Regards,
/Paul
