Why does opening Simulink for the first time in a MATLAB session take a long time?

Regardless of how I open Simulink, when I open it for the first time in a new MATLAB session, it takes almost 15 minutes to open. After the loading process, nothing else in Simulink is slow. How can I speed up this load time?

This is likely due to a known bug related to the default printer being offline:

On Windows, MATLAB appears to stop responding when starting Simulink if either:

• The Windows default printer is set to a physical printer and the printer is offline or not available.
• The driver for the Windows default printer is outdated.

Simulink starts up after some time.

To workaround this issue, set the Windows default printer to a local printer before starting Simulink, and try updating the driver of the printer to the latest version.
