Sorry, this is another Mac rave….
I made my Mac Mini our print server for the household LAN as it sits next to the communal printer. When I did so, I turned off the sleep function as the printer may be needed by anyone at any time and so I had presumed the Mac Mini needed to be awake to serve the print jobs.
While experimenting with remote access, I decided to turn sleep on and see if the Mac Mini would wake from sleep due to a remote screen sharing request. To my surprise and delight it worked. Next I tried printing to the Mac Mini while it was asleep and that worked too! Even if the jobs are sent from the PCs!
Finally a wake from LAN that actually works. I have never been able to get this to work reliably on Windows PCs. I have no idea why this is so hard to do in energy conscious 2011!
I now have a much quieter and cooler office and am doing my bit for global warming thanks to my new Mac Mini.
