Recognize Plug and Play LPT devices

Plug and Play lets an operating system automatically detect and configure hardware, which

simplifies hardware installation and configuration. Like Windows 9x and Me before it, Windows

2000 supports Plug and Play; however, many legacy LPT devices do not. Using hardware hints

(information the device can return in response to requests), Windows can discover the device type

and automatically install support for it.



By default, Windows disables legacy Plug and Play detection. You can add most devices manually,

but it's often much easier to let Windows detect and install the device for you. You can enable

legacy Plug and Play detection on a per-port basis. To enable detection, follow these steps:



Open the Computer Management console and then open the Device Manager.

Expand the Ports branch, right-click the LPT port to which the device is connected, and choose

Properties.

Click the Port Settings tab, select the Enable Legacy Plug And Play Detection option, and then

click OK.

Make sure the device is connected to the specified port and powered on, then restart the computer.





Windows should now detect the device, enabling automatic driver installation and configuration.

After you have the device installed and working properly, disable the option again for the LPT port.
