How can I intercept the content’s of a window’s spool file?

I'm looking to capture and save files that are printed from a client's computer, ideally in text or PDF format. The client might use various software for printing, and I'd prefer not to integrate with each specific software they might use.

Is there a method to intercept the print job content? This could involve programming solutions like Python's win32print or WMI, or perhaps by converting the spool files (.spl & .shd) generated in the C:\Windows\system32\spool\PRINTERS directory during print queuing.
