需要一段python代码打印.eml格式文件

Question

需要一段python代码打印.eml格式文件，GPT给的代码，最后打印出来的是bytes，不是可读的邮件。或者将eml格式转化为msg，再用pywin32打印

 def print_eml(img):
        printer_name = win32print.GetDefaultPrinter()

        # Open the EML file and read its contents
        with open(img, 'rb') as f:
            eml_content = f.read().decode('utf-8')

        # Send the EML content to the default printer
        hPrinter = win32print.OpenPrinter(printer_name)
        try:
            hJob = win32print.StartDocPrinter(hPrinter, 1, ("test", None, "RAW"))
            try:
                win32print.StartPagePrinter(hPrinter)
                win32print.WritePrinter(hPrinter, eml_content.encode())
                win32print.EndPagePrinter(hPrinter)
            finally:
                win32print.EndDocPrinter(hPrinter)
        finally:

以下是使用Python的email和base64模块读取和打印.eml格式文件的示例代码：

```python
import email
import base64

# 读取.eml邮件文件
with open('example.eml', 'rb') as fp:
    msg = email.message_from_bytes(fp.read())

# 获取邮件内容
if msg.is_multipart():
    for part in msg.walk():
        if part.get_content_type() == 'text/plain' or part.get_content_type() == 'text/html':
            content = part.get_payload(decode=True).decode(part.get_content_charset())
else:
    content = msg.get_payload(decode=True).decode(msg.get_content_charset())

# 如果邮件内容经过base64编码，则需要进行解码
if msg['Content-Transfer-Encoding'] == 'base64':
    content = base64.b64decode(content)

# 打印邮件内容
print(content)

```
请确保将example.eml替换为您要读取的.eml文件名，并且根据邮件的编码类型调整代码中的解码方法。如果邮件正文部分是HTML格式，可以使用Python库如beautifulsoup4或lxml来对其进行解析和处理。
