Autoconfig Flow in Windows Vista for PPD

  • Artikkeli

Autoconfig follows the following sequence:

  1. Port Monitor sends to the spooler a notification containing any values that formerly were not in the cache or that changed.

  2. Spooler responds to the notification from the port monitor by calling DrvPrinterEvent.

  3. Printer_Event_Configuration is passed to the driver containing any and all new values. The driver is notified that the value of an attribute has changed. The registry is also updated.

  4. If the notification is too big, a Reduced Schema Event is called.

  5. The PPD file is parsed including all GDL file extensions and GDL content within the PPD. All GDL content in either GDL file extensions or throughout the PPD file must be surrounded with *Ifdef: GDL_Enabled and *Endif: GDL_Enabled.

  6. The IHV plug-in will retrieve the value for *MSBidiValue which will be based on the current string value for *QueryString. For example, a *QueryString value of \Printer.Configuration.DuplexUnit:Installed will represent a *BidiValue value of BOOL(TRUE).

  7. The IHV plug-in will update the driver UI according to the latest configuration.
