SYMPTOMS
When you try to print to a local printer while you are streaming media in Windows Media Player 6.4, you may receive the following error message:

Cannot print to LPT1 the port is in use by another product.



CAUSE
This issue can occur if the streaming media is using dynamic bandwidth as it plays.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

IMPORTANT: This process configures your line speed in Windows Media Player, and prevents it from checking the current line speed.

To work around this issue, configure Windows Media Player to prevent it from checking the current line speed:

NOTE: You may want to set the bandwidth value slightly below the maximum possible value so that you have sufficient bandwidth left over to browse the Web when you are streaming media.

Create a new hexadecimal DWORD registry value named "ManualBandwidth" (in bits per second) in the following registry key:

HKEY_Current_User\Software\Microsoft\Netshow\Player\General

The bandwidth value for the DWORD value should be set to match the download speed of your computer. This setting overrides the Windows Media Player bandwidth detection process that is used when negotiating bandwidth stream. Because of this, the value should be set relative to the download bandwidth of the computer, for example:
 * For a 300kbps speed connection, use a hexadecimal value of 493e0.
 * For a 56kbps speed connection, use a hexadecimal value of fa00.
 * For a 256kbps speed connection, use a hexadecimal value of 3e800.
