如何更改打印机端口 USNIG Win32Print （Python3.11）

问：

我尝试使用以下代码更改打印机端口

import win32ui
import win32print
import time

printer_name = "XP-80C"
desired_port = "USB001"

# Set the desired port for the printer
p = win32print.OpenPrinter(printer_name)
po = win32print.GetPrinter(p,2)
po['pPortName'] = "USB001"
print(po)



try:
    win32print.SetPrinter(p, 2, po,0)
    dc = win32ui.CreateDC()
    dc.CreatePrinterDC(printer_name)
    dc.StartDoc("Print Text")
    dc.StartPage()
except Exception as e:
   
    print(e)

但是我收到这个错误，如何解决？(5, 'SetPrinter', 'Access is denied.')
