Consider the following scenario:
- You have a Windows 8 machine.
- You install a print queue to a SPM (Standard Port Monitor), WSD (Web Services for Devices), or USB (Universal Serial Bus) port.
- After the print queue is installed, you install another queue to the same port.
Having multiple print queues installed to the same port is not a supported scenario. In order for BIDI communication to work, the print queue can only enumerate one print driver.
To ensure Bidi communication works properly, do not install multiple print queues to the same port.
