Horizon 7 Scanner Redirection Performance

We are trying to use scanner redirection from a Windows 10 client to a Windows 10 Guest OS. The drivers for the scanner (Neat Receipts) are installed on the host (machine connecting from) but not on the guest VM. When I check the scanner redirection in the task bar the scanner is listed for both TWAIN, and WIA. It does not matter which connect type I use it takes 40 - 60 seconds before the scanner even starts to scan. Once the scan is done it does show the image quickly (5 seconds) but that initialization time is crazy. Also if I use TWAIN all I get is a black scan, with WIA it does work when my program picks it up. This computer is on the same local network as the horizon server and has a 1GB Cat6 connection back to the server so I don't see it being a performance issue.

Any ideas?
