Windows Batch：使用rundll32处理错误

Question

I'm trying to remove a printer from the user's printer and devices. To make sure that I delete the printer, I have a series of if statements to remove a printer on the network or locally and to remove a printer via name or via name plus server connection.

My problem is that when I test the success of the printer being removed, the errorlevel always reports being 0 regardless of whether the printer was not successfully removed or not.

Does anyone know a way to handle errors with rundll32 printui.dll,PrintUIEntry ?

rundll32 printui.dll,PrintUIEntry /dn /n "%printerName%"
if %ERRORLEVEL% NEQ 0 goto first else (goto after)

:first
rundll32 printui.dll,PrintUIEntry /dl /n "%printerName%"
if %ERRORLEVEL% NEQ 0 goto second else (goto after)

:second
rundll32 printui.dll PrintUIEntry /dl /n \\DC1\%printerName%
if %ERRORLEVEL% NEQ 0 goto third else (goto after)

:third
rundll32 printui.dll PrintUIEntry /dn /n \\DC1\%printerName%
goto after

:after
ECHO If printer was not deleted, click on the 'start' menu button, go to 'Devices and Printers', right click on the printer you want to remove, and select 'Remove Device'

So rundll32 doesn't set an errorlevel , so rather than going through if statements to delete the correct printer, I just removed all printer connections with the code below. This code does no error handling, but it could if necessary.

cscript "C:\Windows\System32\Printing_Admin_Scripts\en-US\prnmngr.vbs" -xc

This batch script was meant to fix network printer's configuration anyways, so I didn't try to delete locally connected printers. Here's my whole script to remove and add network printers in case anyone wants a look.

@ECHO off

ECHO To solve your printer configuration problem, we will first remove the printers having the problem.
pause

REM remove all printer connections
cscript "C:\Windows\System32\Printing_Admin_Scripts\en-US\prnmngr.vbs" -xc
if %ERRORLEVEL% GTR 0 (ECHO If printer was not deleted, click on the 'start' menu button, go to 'Devices and Printers', right click on the printer you want to remove, and select 'Remove Device') else (goto end)

:end
ECHO Continue to printer installation?

pause

REM install printers
start \\DC1\LaserP2055
start \\DC1\LexmarkX544
ECHo The network printers LaserP2055 and LexmarkX544 have been installed
ECHO Would you like to exit the program?
pause
exit
