I installed KB5001567 x64 for Windows 2004. It did not fix the Dymo blank label printing problem. Please also note that we installed the downgrade fix recommended by Dymo, and it did not resolve my problem. Our software is based on a later version of the Dymo SDK, and we cannot access the printer from our software.
Please note that we use this device to print price labels for consigned merchandise, that function is critical to our business. so a fix from Microsoft is very important to us.
