Windows NT/2000/XP Point and Print concept.
- Printers (representing queues to different printers) have data structures called DEVICEMODES attached.
- Standard capabilities are stored in the DEVICEMODE.
- Non-standard capabilities are created by the Win32 printer driver code and stored as key/value pairs associated with the printer.
- Notification backchannel mechanism allows server to notify clients on capability changes and on printer status changes.
