Ira,
I don't see any mention of SERIALNUMBER or SN in 5107.2 - I thought that just standardized the COMMAND SET or CMD values in the device ID?!?

>> Not directly - this identifies the printer, not an individual. If the value was propagated outside of IPP with other personal information it might be used to identify someone ("Mike" printed to a printer with serial number 12345678, it must be Mike Sweet and not Mike Jones). But this is purely informational from the Printer to the Client, for maintenance/support purposes.

>> Last time I checked (but I no longer have a copy...) IEEE-1284 defines SERIALNUMBER (official abbreviation SN, also SER and SERN in the wild) to hold this. But "printer-device-id" isn't something we want in the long term (only needed for drivers) and implementation of the serial number in the device ID is spotty at best...
