使用 PHP powershell 脚本更改默认打印机纸张尺寸

Question

I am trying to change Default printer paper size from PHP

Index.php

<?php
$printer = Shell_Exec ('powershell.exe -executionpolicy bypass -NoProfile -Command "(Get-WmiObject win32_printer | Where-Object Default -eq $True).Name"');

$printer = substr($printer, 0, -1);
$printer = '"' . $printer . '"';
$cmd = ('powershell.exe -executionpolicy bypass -NoProfile -Command ../A5.ps1 ' .$printer);
echo shell_exec($cmd);
?>

A5.ps1

$printer=$args[0]
Set-PrintConfiguration -PrinterName $printer -PaperSize A5

Error

Set-PrintConfiguration : The specified printer was not found. At C:\Users\t4taa\Desktop\phpdesktop\A5.ps1:2 char:1 + Set-PrintConfiguration -PrinterName $printer -PaperSize A5 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (MSFT_PrinterConfiguration:ROOT/StandardCi...erConfiguration) [Set-PrintCo nfiguration], CimException + FullyQualifiedErrorId : HRESULT 0x80070709,Set-PrintConfiguration

When I run script file from PowerShell works fine but from PHP it's refuse to take printer name or miss double quotes, how to resolve this problem.

Answer 1

Why not change the A5.ps1 into

$printer = (Get-WmiObject win32_Printer | Where-Object { $_.Default -eq $true }).Name
Set-PrintConfiguration -PrinterName $printer -PaperSize A5

to have powershell figure out the default printer name AND set the papersize.

That way you can do in the index.php :

<?php
$cmd = ('powershell.exe -ExecutionPolicy Bypass -NoProfile -File ../A5.ps1');
echo shell_exec($cmd);
?>

^{Use -File instead of -Command}
