When you try to connect to a printer shared by a Windows computer, one of the following errors may appear when you enterthe network path or port name:
\\servername\sharename is an invalid port name
Could not connect to the printer: The system cannot find the file specified
Test Page failed to print. Would you like to view the print trouble shooter for assistance? The filename, directory name, or volume label syntax is incorrect.
Test page failed to print. Would you like to view the print trouble shooter for assistance? Unable to create a print job.
Could not start print job.
A StartDocPrinter call was not issued.
These messages are erroneous and occur if the Windows printer share is password protected. If you attempt toconnect to the share by running a NET USE from the command line, you receivethis (correct) message:
The password is invalid for \\servername\sharename
You are allowed to enter the password of the share.
To resolve this issue, use one of the following procedures:
Method 1: Remove the password protection from the Windows printer share.
Make a connection to the share using the command prompt, and then enter the correct password with the following syntax:
NET USE LPTx \\computernamne\printername [password]
Use Print Manager or the Printers folder to create a new printer that uses the redirected LPT port.
