Chipset is one of the processing devices in a computer. It is a number of integrated CIRCUITS, DESIGNED to control how information travels between other components and processor. It is a group of microchip to work as a unit to perform one or more related functions. While motherboard is where all other components like CPU, Memory, Sockets for EXTERNAL connectors and drives are attached. Chipset is a built in feature of otherboard. While, processor is a main integrated CIRCUIT block, which does the function according to the instruction of a computer program. It is based on the logical, arithmetical and input/output of the system.

The customer has installed an INCORRECT Device DRIVER for the Printer. I would uninstall the driver, from the WIndows Device MANAGER and install the CORRECT Device Driver for the Printer from the Disk that came with the Printer. (If the Disk is not available, I can still download the correct device driver from the manufacturer’s website)
