The invention provides an intelligent printer for achieving a power grid operation information classified printing function. The intelligent printer comprises a printing module, a printer control panel, a transmission module and a data processing unit which is connected with the printing module and the printer control panel and connected with a database in an automatic scheduling system through a data interface. A selection button is arranged on the printer control panel and used for selecting transformer substations and time durations required for printing operation information and selecting a form output interface. The data processing unit has access to and calls the operation information of the corresponding transformer substrate and the corresponding time duration in the database of the automatic scheduling system according to the selection of the transformer substation and the selection of the time duration, and executes the corresponding printing operation through the printing module. The transmission module is used for providing the data interface, used for connecting the automatic scheduling system, for the data processing unit. The requirements of specific power grid operation information classified printing are met for monitors, and the output efficiency of the printer is improved.
