I'm running windows 7 ultimate 64bit on my PC, with a samsung printer connected directly to it via USB.
trying to share this printer results in 0x000006cc error.
I tried disabling the firewall but it didn't make a difference.
I made some changes to the homegroup, disabling and enabling printer sharing, but it still didn't work.
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
