A recent hotfix in Windows 11, specifically 24H2, has been found to cause printing issues when using 4D printing commands. This issue is caused by a change in behavior in the Windows PDF driver.

In this hotfix, the driver uses an excessive stack size, generating errors in 4D.

Here are some tests that might solve the issue:

• Separate the execution of printing jobs from the main application process. Use dedicated processes with the command New Process.


• The stack size parameter should be set to a high number of bytes.

In some cases, values ranging from 200.000 and 300.000 bytes in the stack size of new processes solved the issue.
