I have a Samsung SCX-3405FW that when trying to print while the printer has gone to power save, it says offline. I checked the settings on the web interface but it still seems to do it. If I power off then back on the printer, I can print. I looked online about it and someone mentioned that Samsung told them to disable the bi-directional, after trying that, the same issue happens. The printer is on DHCP but I did a static in the router so it has the same IP. I installed the SyncThru Web Admin Service, I can communicate with the printer that way.
