要在 Python 中创建虚拟打印机并连接,需要使用第三方库pywin32。以下是创建并连接虚拟打印机的示例代码:
```python
import win32print
import win32api
# 创建虚拟打印机
printer_name = "My Virtual Printer"
printer_info = {"Description": "My Virtual Printer",
"Name": printer_name,
"Comment": "Virtual Printer for Testing",
"DriverName": "Microsoft XPS Document Writer"}
handle = win32print.AddPrinter(None, 2, printer_info)
# 将虚拟打印机设置为默认打印机
win32print.SetDefaultPrinter(printer_name)
# 打印一份测试文件
job_info = {"Title": "Test Print Job",
"PrintProcessor": "WinPrint",
"DataType": "RAW"}
job = win32print.StartDocPrinter(handle, 1, job_info)
win32print.StartPagePrinter(handle)
win32print.WritePrinter(handle, b"Hello, World!")
win32print.EndPagePrinter(handle)
win32print.EndDocPrinter(handle)
# 删除虚拟打印机
win32print.DeletePrinter(handle)
```
在上述示例代码中,我们使用`win32print`库的`AddPrinter`函数创建了一个名为"My Virtual Printer"的虚拟打印机,并将其设置为默认打印机。接着,我们使用`StartDocPrinter`、`StartPagePrinter`、`WritePrinter`和`EndPagePrinter`函数打印了一份测试文件。最后,我们使用`DeletePrinter`函数删除了虚拟打印机。
