Hi,
I would like to suggest you perform the following troubleshooting suggestions:
1. Uninstall the printers and only install one of them to check if it is a printer driver confliction issue.
2. Test the issue in Clean Boot to check if this is a software confliction issue.
3. If both tests cannot work, please refer to the following link and perform the troubleshooting steps manually.
