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. The releases affected by this bug are from R2015b to R2017b. See the link below for more information.

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• The driver for the Windows default printer is outdated.

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.
