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，我无法下载任何像iTextSharp这样的第三方软件来完成这项工作。

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。是否有可能使新文件名与原始文件名匹配？

此外，该过程如何实现自动化，因此不需要用户输入（即输入文件名或按下打印）？最后，是否可以更改打印目录？

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

这是我会怎么做：

#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
