Problem
Microsoft released Windows updates for the current client and server operating systems in June 2020, which appear to cause problems on certain systems. In this case, the print could not work or even the entire application could be terminated unexpectedly, which can also lead to data loss.
The creation of PDF documents using the PDF software printer driver from Microsoft may also be affected. The error has already been confirmed by Microsoft and the updates for the Print Spooler service have been identified as the cause.
However, since List & Label makes extensive use of the Windows printer system, the print functions of List & Label may also be affected.
Microsoft is aware of this problem and is already working on a solution. For more details, see the release notes from Microsoft at the following link: Print spooler might error or close unexpectedly when attempting to print
Workaround
The only way around this behavior is to uninstall the update KB4557957 (Windows 10 Version 2004) or KB4560960 (Windows 10 Version 1903).
