If you have not already, please consult with a support person prior to using this printer for the first time. We need to setup an account in order for you to use the system. You can access the printer here . You will find a complete listing of user manuals at this web location.
File size can be a problem for the web interface.
Use the FTP option for large files. You will not be warned of this by the printer. It simply does not print your file. Your account is NOT charged if this happens. File scaling can be selected from the web browser interface.
