CentreWare Internet Services (CWIS) is a very useful tool available on networked printers. CWIS is the embedded HTTP server application that resides in the printer. Internet Services allows Administrators and Users to modify network and system settings on the printer from the convenience of their computers or tablets. The CWIS allows you to program and check the status of the machine from the comfort of your office or cubicle. I love this feature because I can do so many things without having to touch the printer. This can save me time and the CWIS interface is so easy to use. I can check the status of the printer, the paper trays and the consumables. I can check settings and actually change settings from the CWIS screens. Please be aware that some changes may require the Administrators password. I can even upgrade the machines firmware from the CWIS.
