Everything Wrong since i have ugrade to Parallels 12

1) Imac become very slow when parallels is up
2) Printer doen't work in Mac when it's actived in Paralells
3) Symbol Bar code Scanner is very very Slow in Windows when it's not actived in External peripherical, But i's ok with Mac. If it is actived it's ok with Windows but no longer with Mac
3) Screen Energie Saver doen't work on Mac when Parallels is Up

So can you help me (speeking french ?) or Can you tell me how to downgrade to Parallels 10 which was better for me

Hello hydragon,
Please try to reinstall Parallels tools manually and check if that makes any changes.
 
installed parrallels 12 on my sierra iMac 2011 after blissfully running parallels 11 with the same set up, what a mistake my windows 10 is now painfully slow like pulling teeth. What going on? i don't want to down grade to parallels 11 as I've paid for 12, please fix as i am obviously not alone
