单击Windows打印按钮保存文件

问：

单击打印按钮保存文件

我想创建一个python第三方应用程序，它执行以下操作。 当我打开一个文件（docx、pdf 或 csv）并打开打印对话框并单击打印时。单击打印后，它应该将文件保存在本地目录中，即 d：/prints 。请注意，在我的应用程序中，即使打印机或打印机处于离线状态，也应该能够保存文件。我尝试了多种方法，但我无法实现我的目标。你能帮帮我吗？谢谢

我遇到了下面给出的这段代码，这就是它的工作原理： 当我打开一个文件并按ctrl + p时，它会在prints目录中创建一个空的损坏的pdf。这不是我想要的结果，我希望在单击打印按钮时，它应该在目录中保存或复制文件。

import ctypes
import time
import os

save_directory = "D:/prints"


def is_ctrl_p_pressed():
    return (ctypes.windll.user32.GetKeyState(0x11) & 0x8000) != 0 and \
        (ctypes.windll.user32.GetKeyState(0x50) & 0x8000) != 0


try:
    while True:
        if is_ctrl_p_pressed():
            print("Ctrl+P was pressed. Detected print action.")

            # Check if the save directory exists, and create it if not
            if not os.path.exists(save_directory):
                os.makedirs(save_directory)

            # Generate a unique filename for the saved print document
            current_time = time.strftime("%Y%m%d-%H%M%S")
            save_filename = os.path.join(save_directory, f"print_{current_time}.pdf")

            # Replace the following line with your code to save the print job to the specified file
            # You might need to access the print spooler or printer driver to do this
            # For simplicity, we'll just create an empty file here.
            with open(save_filename, 'w') as f:
                pass

            print(f"Print document saved to: {save_filename}")
        time.sleep(0.1)  # Adjust the sleep duration as needed
except KeyboardInterrupt:
    pass
