QLn2020 TLS v1.2 support

Tags: 

Hi All,

I have some QLn2020 printers with Software FW Version D68.20.15Z that connects via Weblink to a service hosted on a Windows Server. All has been working fine until we disabled TLS v1.0 and v1.1 on the Windows server. Can anyone confirm if this model of printer supports TLS v1.2 or not?

Here's the connection log from the printer and you can see it's trying to use TLSv1.

The TLS v1.2 is supported.

The TLS v1.2 is supported. See the weblink logs below, in which you can find the statement of "SSL connection using TLSv1.2".
