It is just a basic test and if it fails this basic test the driver should not be implemented in your environment.

Shared Mode — The print driver is run in a separate process from the spooler and other print drivers can share this process. Isolated — The printer is running completely in its own isolated process and no other printers can share this process. None — The normal operation of the printer driver being run directly by the print spooler process. Some drivers can share the process and some cannot. It all depends on how the driver was designed. Contact the manufacturer of the printer driver to confirm this.

Test the drivers in the environment and inspect which drivers need to be isolated. Ideally any driver that has to be isolated should not be used, as that is an indication of a problematic driver. Though isolating the process can help keep the print spooler more stable it still does not fix the driver. So if a problematic driver is found, contact the manufacturer of the driver to have it corrected, or verify if they can recommend a replacement driver.

Because the name of the driver is the same, it does not necessarily mean that the driver is actually the same.
