调用powershell脚本后，批处理文件不会继续

Question

I have a situation. I'm installing network printer on remote desktops using a batch file that calls up a Powershell script, but after printer is installed on the remote desktop, Powershell returns nothing - so my batch file wont be able to continue...I must manually hit ENTER twice to make it echo DONE and run the rest of the scripts. Any idea why?

@echo off

Copy /Y "\\AddPrinter\AddPrinter.ps1" "C:\scripts" 

powershell.exe -ExecutionPolicy Bypass -Command "C:\scripts\AddPrinter.ps1" 

Echo DONE

Del /F /Q "C:\ntfs3\scripts\AddPrinter.ps1"

This is my powershell script, I even put a exit in the end of script, but powershell on remote pc just wont exit.....so it will not return to batch

$PrinterPath = "\\server-01\Printer0101"
$net = new-Object -com WScript.Network
$net.AddWindowsPrinterConnection($PrinterPath)
exit

BTW, I m using psexec to call up this batch file with a txt file containing all pc names.

psexec @%1 -u admin -p xxxxxx -c -f "C:\AAA\AddPrinter.bat"

I did some research, some one said need to use call with %1 > null to make Powershell return to batch. But it does not work either.

Call powershell.exe -ExecutionPolicy Bypass -Command "C:\scripts\AddPrinter.ps1"  %1 > null

I could only use batch command to install printer, but after installation, the new printer always setup as a default printer. but if use powershell to install it, it wont change default printer on remote desktop.

rundll32 printui.dll PrintUIEntry /ga /n\\server-01\printer0101

Hint please.

Answer 1

I have regularly seen problems calling PowerShell through psexec.exe . I would recommend ditching psexec.exe and configuring PowerShell Remoting instead. Then, you can deploy your script using the Invoke-Command command.

Answer 2

I could also suggest for DOS like commands to use invoke-expression . PowerShell will process the command that you are passing as it is. The great is that you will be able to pass also variables
