Question

我正在编写一个小的ps1脚本来清除队列并在最终用户选择的打印机上重新启动假脱机。到目前为止，我在预定的机器上使用默认打印机，但我需要最终用户能够准确选择哪个打印机给他们带来问题。这是当前的功能脚本：

net stop spooler

Remove-Item C:\Windows\System32\spool\PRINTERS\* -Force

net start spooler

$printer = Get-WmiObject -Query " SELECT * FROM Win32_Printer WHERE Default=$true"

$PrintTestPage = $printer.PrintTestPage()  

$wshell = New-Object -ComObject Wscript.Shell

$wshell.Popup("I found a problem that I was able to fix.  Please try to print again.",0,"Printer Helper",0x1)

我尝试按以下方式更改脚本以允许用户输入。

    net stop spooler

Remove-Item C:\Windows\System32\spool\PRINTERS\* -Force

net start spooler

get-printer

$printer = Read-Host -Prompt 'Please Type In The Name Of The Printer That You Are Having Problems With'

$PrintTestPage = $printer.PrintTestPage()  

$wshell = New-Object -ComObject Wscript.Shell

$wshell.Popup("I found a problem that I was able to fix.  Please try to print again.",0,"Printer Helper",0x1)

但是，我收到以下错误。

方法调用失败，因为[System.String]不包含名为＆＃39; PrintTestPage＆＃39;的方法。

我该如何解决这个问题？

Answer 1

Read-Host返回一个字符串 - 不是Win32_Printer wmi类的实例。

您可以使用Read-Host的输入来检索实例：

$PrinterName = Read-Host 'Please Type In The Name Of The Printer That You Are Having Problems With'

$PrinterInstance = [wmi]"\\.\root\cimv2:Win32_Printer.DeviceID='$PrinterName'"

# Now you can call PrintTestPage()
$PrinterInstance.PrintTestPage()

如何将测试页打印到指定的打印机？
