System:
Windows 7 64
TP-LINK TL-PS310U printer server
Epson RX500 printer
When I upgraded from 5.2.2 to 5.2.7 I found I could not connect to my printer via the TL-PS310U printer server.
I was however able to see the server and that the printer was connected to it!
Networx was configured to ignore local traffic.
The upgrade was undertaken as part of a fresh windows install so took many hours of head scratching to find the solution.
Down graded to my old copy of 5.2.2 and all seems fine.
