### PrtSet Parameter - pInData

pInData (PVOID) - input Contains either a command sequence to pass to, or information required by, the printer.

If ulCommand is set to BIDI_SEND_PASSTHRU, pInData contains the command sequence to pass to the printer. The field will not be altered by the port driver or protocol converter unless ulType is set to TYPE_WITHOUT_WRAPPER.

If ulCommand is not set to BIDI_SEND_PASSTHRU, pInData may contain information required by the command (see BIDI Command Structures and Command Flow for more information).
