Receiving error when parsing session log file

We're using WinSCP to post files to an SFTP server. When we try to post the file, we're receiving the error:

Error parsing session log file - Error output was "Error occurred during logging. Cannot continue. System Error. Code: 28. The printer is out of paper"

There are no printers associated with this process. Can someone help get us past this error?

Please attach a debug log file showing the problem (using the latest version of WinSCP).
Set Session.DebugLogPath.

We also need to know how exactly are you using WinSCP/running your code?
