    Awesome suggestion, my errant Mac wasn't sleeping either and as soon as I removed the stuck printer, all was well Thanks!

    Yes, not something you would think could cause sleep issues! Thanks for your feedback!

    I had the same problem where my MacBook pro (mid 2009) will not sleep when plugged in. Repairing disk permissions and deleting all my printers from system preferences helped. Not it goes to sleep with no hussle

    Same fo me. It was trying to send a job to a printer that wasn't accessible and once I deleted it from my preferences, it slept as usual.

    I too could not get my MacBook Pro to sleep.  I tried a number of suggestions in the discussions.  One suggested to delete printers that seemed to be experiencing a problem.  This seemed to work.  My MacBook Pro is now sleeping again.  Thanks.

    Fantastic! I'd been trying to solve this problem for weeks. Epson Stylus driver with jobs stuck in the print queue.

    following the "solved" solution didn't work for me, then i deleted the printer from the Print & Scan system preference. That didn't immediately work (i hadn't restarted at that point). I then moved all the preferences associated with printers to the desktop (same as deleting them, but you're backing them up too).

    i.e. removed any com.apple.printer..... preference and any com.epson..... preference (i only have an epson printer.

     

    I then restarted and it FINALLY (after years) sleeps with the lid open

     

    Thanks guys

    had the same problem, tried extra programms etc.

     

    not a computer geek, so had no idea how to delete mentioned files etc

     

    I could not click on "open printer status" (in German as on screenshot: "Drucker-Warteliste öffnen"), it did not open so I couldn't clear any outstanding print jobs there...

     

    For those guys who have no clue, my simple solution:

     

    (my system runs in German, not sure what the exact name of the things are)

     

    - switch off your printers/scanners

    - go to sytem

    - select printer and scanners

    - on left side see list of your printer(s)

    - do a right click on one of them

    - choose "reset print system" (last option mentioned)

     

    All printers/scanners will be deleted.

     

    Then switch your printers/scanners back on.

    Click on the + to add them again, and they will appear and add them back to your list.

     

    Worked for me!

     

    Good luck!sleep problem.jpg

    Briljant tip, had problems with letting my MBP go to sleep since I upgraded to ML. Used the above tip for my 4 printers and the problems where gone. Thanks you all!
