可以通过以下步骤实现:
win32print
库。可以使用以下命令安装该库:win32print
库。可以使用以下命令安装该库:完整的Python代码示例如下:
import win32print
import win32ui
import win32con
file_path = "path/to/png/file.png"
image = win32ui.CreateBitmap()
image.LoadImage(file_path)
printer_name = win32print.GetDefaultPrinter()
printer_handle = win32print.OpenPrinter(printer_name)
properties = win32print.GetPrinter(printer_handle, 2)
devmode = properties['pDevMode']
devmode.PaperSize = win32con.DMPAPER_A4
devmode.Orientation = win32con.DMORIENT_PORTRAIT
win32print.DocumentProperties(0, printer_handle, printer_name, devmode, devmode, 0)
job_info = ("Python Print Job", None, {"DesiredAccess": win32print.PRINTER_ALL_ACCESS})
job_handle = win32print.StartDocPrinter(printer_handle, 1, job_info)
win32print.StartPagePrinter(printer_handle)
h_dc = win32print.GetPrinter(printer_handle)['hDC']
h_dc.StartDoc("Python Print Job")
h_dc.StartPage()
h_dc.BitBlt((0, 0), (image.GetWidth(), image.GetHeight()), image, (0, 0), win32con.SRCCOPY)
h_dc.EndPage()
h_dc.EndDoc()
win32print.EndPagePrinter(printer_handle)
win32print.EndDocPrinter(printer_handle)
这段代码将加载指定路径的PNG文件,并将其发送到默认打印机进行打印。请注意,代码中的"path/to/png/file.png"
需要替换为实际的PNG文件路径。
