Value
Description
1

Auto-detect mode. The spooler will use the results of BIDI_Q_PORT to decide
if BIDI should be enabled and which protocol converter to use. This is the
default.
2
PRPORT_DISABLE_BIDI
BIDI disabled. The spooler will not use the printer in BIDI mode. This overrides
the port driver.

to use. The application must also supply the protocol converter name when
setting a port to this mode.
