Sign-in is not automatic first time on Microsoft Entra joined computer

Sign-in to the Printix Client is automatic on Microsoft Entra joined Windows 10 and 11 computers and works with the Pro, Enterprise, and Education editions. Microsoft does not support Microsoft Entra join on Windows Home editions. However, if you have not accepted Printix for all users, users will be prompted to accept this the first time they sign in.

Resolution: Verify that Printix is accepted for all users, so the automatic sign-in to the Printix Client works on Microsoft Entra joined Windows 10 and 11 computers.

If more than one Microsoft Entra directories exist, sign-in to the Printix Client is no longer automatic the first time on Microsoft Entra joined Windows 10 and 11 computers. The user must select a directory (acme.com or ajax.com) and then sign in, but only the first time.
If you have either renamed the Printix Client installation file, or are installing through Microsoft Endpoint Manager and have not specified the Command line arguments, this also breaks the SSO, because the sign-in occurs through sign-in.printix.net/tenanthub.
