Python編程控制打印機節能模式

class Printer:
    def __init__(self, model):
        self.model = model
        self.energy_saving_mode = False

    def print_document(self, document):
        if self.energy_saving_mode:
            print("Printer is in energy saving mode. Cannot print document.")
        else:
            print(f"Printing document: {document}")

    def enable_energy_saving_mode(self):
        self.energy_saving_mode = True
        print("Energy saving mode enabled.")

    def disable_energy_saving_mode(self):
        self.energy_saving_mode = False
        print("Energy saving mode disabled.")

# Create a printer object
printer = Printer("HP LaserJet")

# Print a document
printer.print_document("Sample document")

# Enable energy saving mode
printer.enable_energy_saving_mode()

# Try to print a document in energy saving mode
printer.print_document("Sample document 2")

# Disable energy saving mode
printer.disable_energy_saving_mode()

# Print another document
printer.print_document("Sample document 3")

這段代碼定義了一個Printer類，其中包含打印機的模型和能源節能模式的狀態。通過print_document方法打印文檔時，會檢查是否處于能源節能模式，如果是則無法打印文檔。通過enable_energy_saving_mode和disable_energy_saving_mode方法可以控制打印機的節能模式狀態。最后創建一個Printer對象，演示了如何使用這個類來控制打印機的節能模式。
