What is the purpose of the Additional Drivers button in the Sharing tab of the Printer Properties?

• to add additional drivers for other operating systems
• to add additional drivers for other printers in the network
• to add additional drivers for duplex printing
• to add additional drivers for other printers connected to the computer
  

  Explanation: The Additional Drivers button loads drivers in the sharing computer for other operating systems that the client computers may be running. For other printers in the network, the drivers must be loaded in the computers sharing the other printers. There is no need for additional drivers for duplex printing. The required drivers for other printers connected to the sharing computer will be loaded automatically.
