During our last Cloud Imaging Model WG meeting, we discussed having the ability to explicitly cancel a previous Identify-Printer operation. The consensus during that meeting was to add a new "identify-actions" keyword ('cancel') that would cancel any active identification mechanism.
In addition, a new "printer-state-reasons" keyword ('identifying-printer' was proposed, although given the existing 'identify-printer-requested' value I like adding 'identify-printer-active' instead) would be added to allow a Client to discover whether a printer is currently identifying itself using an action other than 'cancel', which by definition stops any active identification and removes the new keyword from the "printer-state-reasons" attribute...
The official registration would look like this:
Attributes (attribute syntax)
Keyword Attribute Value Reference
identify-actions (1setOf type2 keyword) [PWG5100.13]
printer-state-reasons (1setOf type2 keyword) [RFC2911]
(I considered adding this to IPPSIX, but since this has application outside of shared infrastructure/cloud deployments I think we should register it separately...)
