Microsoft has confirmed a known issue that may prevent network printer software from discovering and installing the network printer on systems with low memory (< 4GB).  This is due to firewall hardening rules added in Windows 10 Version 1703.

Was supposed to be fixed in https://support.microsoft.com/en-us/help/4020102/windows-10-update-kb4020102 WAS NOT FIXED at that time.

Appears to be fixed in https://support.microsoft.com/en-us/help/4022716/windows-10-update-kb4022716
