ECP Port with SMC Chip Set Does Not Transfer Data Properly

 * }

Q139204

-

The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
When you are using a parallel port that is configured for extended capabilities port (ECP) mode, you may be unable to print to a printer that is connected to the port, or to use a connection made with Direct Cable Connection that uses the port. The print job may seem to be printed correctly, or the data may seem to be transferred correctly, but some of the data sent to the port may be damaged.

This problem is known to occur with ECP ports that use an SMC chip set. The following computers are known to contain ECP ports with the SMC chip set:


 * Hewlett-Packard (HP) Vectra

CAUSE
This problem can occur if the ECP port is not properly initialized. Many ECP ports with the SMC chip set are not properly initialized when the computer is started.

RESOLUTION
To resolve this problem, use any one of the following methods:


 * Configure the parallel port so that it is not in ECP mode. For information about how to do so, please consult the computer's documentation or manufacturer.
 * Use the SMC Setup disk included with your computer to reconfigure the ECP port so that it is properly initialized when you start the computer. To obtain the SMC Setup disk, or for information about how to use the disk to configure the ECP port, please consult the computer's manufacturer.
 * Obtain a newer version of the SMC chip set that resolves this problem from the computer's manufacturer.
