Apparatus and method for metering and monitoring printer related data on non-networked printers
This invention relates to an apparatus for monitoring a locally attached printer using the locally attached printer's Ethernet interface. A USB device is installed between a computer and a locally attached printer and additional connects to the printer via an Ethernet interface. The USB device uses SNMP (or other network protocols) to manage the printer via the Ethernet interface. The system may then report the management information to a central server.
1. A device for monitoring a non-networked printer, the device comprising:
a first USB interface interconnecting with a USB port on a workstation, wherein the first USB interface is a female USB-B port;
a second USB interface interconnecting with a USB port on the non-networked printer wherein the second USB interface is a female USB-A port, wherein the first USB interface is connected with the second USB interface in order to pass USB data between the first and second USB interfaces;
an Ethernet interface interconnecting with an Ethernet port on the non-networked printer;
an Ethernet MAC and PHY configured to encode and decode Ethernet data received and transmitted via the Ethernet interface;
a WIFI module interconnecting with a wireless network;
a voltage regulator configured to regulate power supply on the first USB interface in order to provide power to the USB device;
a webserver module;
an Ethernet module connected with the Ethernet interface, the Ethernet module comprising:
an SNMP module running an SNMP Manager which receives printer-related device information from the non-networked printer via the Ethernet interface; and
a central control module connected with the Ethernet module, and WIFI module, which receives instructions from a remote server to initiate SNMP queries to the printer via the Ethernet module and returns SNMP information to the remote server.
