How windows handles print jobs

How Windows Handles Print Jobs

  • Windows NT/2000/XP or Windows 9x using a PostScript printer

    • Converts print job data to PostScript language

    • Windows 2000/XP can also use Printer Control Language (PCL)

  • Windows 9x using a non-PostScript printer

    • Converts print job data to Enhanced Metafile Format (EMF)

How Windows Handles Print Jobs (continued)

  • Text data lacking embedded control characters is sent as raw data (DOS)

  • Spooling

    • Printing jobs are placed in a queue, so the applications finish printing ASAP

    • The queued jobs are served by FCFS (First Come First Serve)
