从 CSV 安装网络打印机

Question

我编写了一个脚本来将用户配置文件备份到网络共享。我的老板也希望它备份和恢复网络打印机。该脚本包括以下 PowerShell 行...

Get-WMIObject -class Win32_Printer -computer $env:computername | Select Name | Export-CSV -path '\\share\printer_export.csv'

这会将所有打印机导出为 CSV。值如下所示。

#TYPE Selected.System.Management.ManagementObject
Name
Snagit 10
Microsoft XPS Document Writer
\\\server\printer1
\\\server\printer2
\\\server\printer3

我编写了另一个脚本来将用户配置文件从备份复制到当前登录的计算机。这包括以下 powershell。

$PrinterList=IMPORT-CSV \\share\printer_export.csv
FOREACH ($Printer in $PrinterList) {
    Invoke-Expression 'rundll32 printui.dll PrintUIEntry /in /q /n $Printer'
}

$Printer 变量应该返回值\\\server\printer1 从而从命令行安装打印机......但没有任何反应。我哪里做错了？

另外，我怎样才能让它忽略不以“\”开头的任何 CSV 行？

下面的答案解决了这个问题。

这是完整的脚本。它目前备份用户配置文件、签名、任务栏图标、outlook pst、chrome 书签、itunes 移动备份、高级颜色 reg 设置、桌面壁纸、将打印机导出到 csv

REM COPIES THE VARIABLE TO THE USERS BACKUP
xcopy $wallpaper "\\server\$env:username\Wallpaper\"

Get-WMIObject -class Win32_Printer -computer $env:computername | Select Name | Export-CSV -path '\\server\$env:username\printer_export.csv'

这是恢复脚本。对 PC 进行映像后，我运行此脚本将所有内容放回原处。

REM launches exe from the server, points at the wallpaper folder, randomly selects image, converts to bmp and copies it to the users theme folder then sets as wallpaper

Answer 1

这两个问题都非常简单...您出错的地方是，当您导入 CSV 时，它会创建一个对象数组。每个对象都有一个属性Name。当您引用该对象时，您需要指定要使用的属性，因此您的Invoke-Expression 行应该是：

Invoke-Expression 'rundll32 printui.dll PrintUIEntry /in /q /n $($Printer.Name)'

这将扩展名称，此时它应该可以按预期工作。至于让它跳过不以“\”开头的条目，您可以执行以下操作：

FOREACH ($Printer in ($PrinterList | Where{$_.Name -like "\*"})) {

这只会将以“\”开头的条目传递到ForEach 循环中。
