使用 Powershell 将 PDF 打印到 XPS

Question

我想使用 Powershell 将包含 PDF 文件的文件夹转换为 XPS 文件。由于系统限制，我无法下载任何第三方软件，如 iTextSharp 来完成这项工作。

我已经能够让 Powershell 打开文档并打开 XPS 的打印窗口，但名称始终为空白。新文件名可以和原文件名匹配吗？

此外，该过程如何实现自动化，从而不需要用户输入（即输入文件名或按打印）？最后，是否可以更改打印到的目录？

Get-ChildItem -path $pdf_filepath -recurse -include *.pdf | ForEach-Object {Start-Process -FilePath $_.fullname -Verb Print -PassThru | %{sleep 10;$_} }

我会这样做：

#Define the directory containing your .pdf files
$mydir="$env:USERPROFILE\Desktop\New folder"
function print_files($mydir){
    #The purpose of this counter is to number your .xps files
    Get-ChildItem $mydir -Filter *.pdf -Recurse | Foreach-Object {
        #For each .pdf file in that directory, continue
        same_time $_.FullName
    }
}
#The following function keeps checking for a new window called "Save Print Output As". When the window shows up, it enters the name of the file and press ENTER.
function enter_my_names($fullname){
    $wshell = New-Object -ComObject wscript.shell;
    while($wshell.AppActivate('Save Print Output As') -ne $true){
        $wshell.AppActivate('Save Print Output As')
    }
    $basename = [io.path]::GetFileNameWithoutExtension($fullname)
    #This is where the name is actually entered
    $wshell.SendKeys("$basename")
    $wshell.SendKeys("{ENTER}")
}
#The following function launches simultaneously a print job on the input file and a function waiting for the print job to show up to name the file.
workflow same_time{
    Param(
        $fullname
    )
    parallel{
        Start-Process -FilePath $fullname –Verb Print -PassThru
        enter_my_names($fullname)
    }
}
#MAIN PROGRAM
#Here the script saves your current printer as default
$defprinter = Get-WmiObject -Query "Select * from Win32_Printer Where Default=$true"
#Queries for a XPS printer
$printer = Get-WmiObject -Query "Select * from Win32_Printer Where Name='Microsoft XPS Document Writer'"
#Sets the XPS printer as Default
$printer.SetDefaultPrinter()
#Starts the main job
print_files($mydir)
#Sets the old default printer back as default again
$defprinter.SetDefaultPrinter()
#This is a small delay to be sure everything is completed before closing Adobe Reader. You can probably shorten it a bit
sleep 5
#Finally, close Adobe Reader
Get-Process "acrord32" | Stop-Process

干杯！
