I had a prompt to update my Parallels installation this morning, so I let it do the update. Afterwards, Windows 8.1 doesn't "see" any printers (in Control Panel, they're all grayed-out). On the OS X side, the printer works fine. The printer was connected wirelessly and is now plugged in via USB - still no change. When I first attached it via USB, I got the pop-up asking which "OS" to connect it to. I even told it connect to Windows but it didn't help (I found it when I do this, it's not available to OS X vs vis-versa where Win8.1 will see my OS X printers fine (normally)). I fixed that by un-checking it from the Devices menu. I do have "Add all Mac printers" and "Synchronize default printer" checked. Un-checking and re-checking them didn't fix it either. I have restarted Windows and restarted Parallels. I haven't restarted OS X but it's my next step....
