hi,
This problem may occur if the printer driver does not use Plug and Play for its installation.The following registry key has become damaged:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\LPTENUM

Some Plug and Play devices that use a parallel port, such as early versions of Iomega Zip drives, may not be detected by Windows.

1.Right-click the My Computer icon on your desktop, and then click properties.
2. Click the Hardware tab, and then click Device Manager.
3. Click the [+] symbol to expand Ports, right-click Printer Port (LPT1) (or ECP Printer Port (LPT1)), and then click Properties.
(Note: If you have more than one printer port installed on your computer, click LPT2 or LPT3.)
4. Click the Port Settings tab, check Enable legacy Plug and Play detection, and then click OK.
5. Restart your computer when you are prompted to do so.
