Even though the default Show informational notifications for network printers is checked on the Advanced tab of Server Properties, you don't receive any notification.
To workaround this behavior:
1. Copy / Paste the following to a NetPrtNotify.reg file:
Windows Registry Editor Version 5.00
2. Merge the NetPrtNotify.reg file with your registry, or run regedit /s NetPrtNotify.reg.
3. Log off and log on for this setting to become effective.
