I have reported this to Castelle and they told me it is a feature for
troubleshooting, however they will make the change the next time they
release the Faxpress Software. I just thought that other admins should be
made aware so they can check their systems are secured correctly.
Printing can be configured to use either a printer connected directly to
the parallel port of the fax server or to a Network print queue. When
configuring the system to use a Network print queue the following
information needs to be entered.
NT Host Name
Printer Shareable Name
If the login name is either entered incorrectly or changed by a user,
when a document is sent to the print queue an error event will be added to
the notices, This error divulges the following information.
Notice: Network Print Queuing Error For Job XXXX
Notice For: Faxpress Username
Queue: Printer name
Server: NTPrint Server
Login: Login, Password
Error At: Time
The Login credentials, including the password are shown in Plain text.

To re-create the 'feature'

The username "John1" and his password are presented.
