有没有办法在PHP中存储通过Windows PC发送的打印作业？

Question

I am working on a project for school. I am wondering if there is a way in PHP to listen for print jobs and store them once received? I currently have a webserver that is accepting webhooks from other applications, parsing out the JSON and storing in a MsSQL. Is this the wrong path to take? thanks

Ok – I don’t know if this is a solution but here is my attempt at trying to help :)

General assumptions:

1. PHP is the server side language used in all instances (the theory should work with others as well – using PHP as the question was tagged as such)
2. Sender and receiver servers are different (it is more easier if both are on the same box – but not a show stopper)
3. Access to both sender and receiver webservers
4. Windows set up (WAMP or alternative)
5. You are securing your set up / directory accesses as you go along

Option 1 (Custom sender / receiver)

On the box that is sending the print request:

• Create a PHP script to output the files to a temp directory
• Create file with required extension (please see documentation if required)
• Put contents
• Close connection / file - https://www.php.net/manual/en/function.file-put-contents.php
• Use powershell or alternative to put the files in the temp directory into a remote directory on the

• Run this at an interval of your choice

On the box that is receiving the file:

• Create a PHP script to read files on remote

• Show files to print in a list which can be downloaded to local terminal / device and printed

Option 2 (Leverage an existing print server)

In this option you would only need to amend the sender webserver config: [inspired by: https://www.hashbangcode.com/article/printing-directly-php]

• Download php_printer.dll for your version (https://windows.php.net/downloads/pecl/snaps/printer/0.1.0-dev/)
• Enable in php.ini via: printer.default_printer=PHP_INI_ALL extension=php_printer.dll

• Set the printer as your print server address and send your output to print directly from the Webserver as follows from your application:

  ` $data= "Hello"; printer_set_option($ph, PRINTER_MODE, "RAW"); printer_write($ph, $data); printer_close($ph); } else "Couldn't connect..."; ?>'

Option 3 (Use a plugin): https://www.neodynamic.com/products/printing/raw-data/php/
