Overall Limitations This overall configuration provides a high level of network security for HP MFPs. At the same time, it introduces some limitations to the conveniences designed into the MFPs. Following is a list of known effects of this overall configuration: • Extra steps to use MFPs: Users will be required to provide usernames and passwords at the control panels before they can use the MFPs. • The MFPs will not allow a user to cancel the print jobs of other users. The user would have to go to the person who submitted the job and ask that person to cancel it. • Extra steps for printing faxes: A user will be required to provide a fax PIN before printing a fax. • No Embedded Web Servers: Disabling EWS Config disables the entire EWS feature. • No way to change the From Address on email send jobs: Depending on the capabilities of your network, the MFPs will place either a default from address or the user's email address of the user who logged into the MFP. It will provide no method to change it. 45
