The release notes for SPAR release 071.010.103.23400 states that Airprint is included and enabled by default so no extra DLM file should be required.
The Airprint enablement DLM was only requried for the initial release version of ConnectKey, as Airprint had not been certified by Apple in time for the launch of ConnectKey.
I upgraded a WC7830 to Spar release “071.010.103.23400” to solve the SMB problem with scanning. that worked, however now I don't have a compatible AirPrint dlm to install. is there any way to find an airprint patch that works with 071.010.103.23400 so I don't have to re-install the entire machine back to a 044xx verion of the firmware?
