打印机扫描要驱动

A4

A printer driver is a piece of software that acts as a bridge between a computer and a printer. The driver is responsible for converting the data from the computer into a format that the printer can understand and then sending it to the printer. It also allows for the printer to communicate back to the computer with any errors or status updates. In general, the driver will be specific to the type of printer being used and must be installed to the computer before the printer can be used.
