Windows批处理:使用rundll32处理错误

Question

我试图从用户的打印机和设备中删除打印机。为了确保删除打印机，我有一系列if语句来删除网络上或本地上的打印机，并通过名称或名称+服务器连接删除打印机。

我的问题是，当我测试正在删除的打印机的成功与否时，无论打印机是否成功删除，errorlevel总是报告为0。

有人知道用rundll32 printui.dll,PrintUIEntry处理错误的方法吗？

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'

因此，rundll32不设置errorlevel，因此，与其通过if语句删除正确的打印机，我只是删除了与下面代码的所有打印机连接。此代码不进行错误处理，但如果有必要，则可以。

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

这个批处理脚本无论如何都是为了修复网络打印机的配置，所以我没有尝试删除本地连接的打印机。这里是我的整个脚本，以删除和添加网络打印机，以防有人想看。

@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
