Exact same problem here with a Brother MFC-495CW - worked fine until the most recent Windows update (6/9/20).
The printer can print its internal test print, but print jobs through Windows appear in the queue, then just disappear. No response of any kind from the printer.
I tried removing the Adobe Flash security update as mentioned by another poster, but that did not resolve the issue.
Anyone have any other ideas? I have tried uninstalling, reinstalling, etc. several times. Tried connecting to different USB ports, and connecting to the router. Nothing works.
Microsoft, will you be releasing a fix???
