A new version of DLS is available that resolves this issue. This will need to be installed on any client machine experiencing the slow printing issue. You can download it here:
The above version of DLS is now live on DYMO.com for all regions.
Since 4/23/2018 all users of the windows version of our SDK have been experiencing a 10-15 second slowdown. The issue can also cause performance issues when opening label files in DLS. This appears to be caused by our code attempting to contact 22.214.171.124 (http://www.w3.org/1998/XMLSchema) in order to validate each label before printing.
We have identified a fix for this issue and we are currently expediting a test cycle so we can release a patch as soon as possible.
Until the actual fix goes out, users can alleviate this slowdown by preventing this call. We have seen success with two methods thus far.
- Prevent connections to 126.96.36.199 (http://www.w3.org/1998/XMLSchema)
- Use the windows defender firewall to prevent DYMO.DLS.Printing.Host.exe from making outbound connections.
We apologize for the inconvenience, and will update this post as soon as the situation has been resolved.
