Seems a rather strange advice to me. But you're rather vague about what happens.
1. What exactly is 'periodically winking off'? Every 10 seconds, every hour, everytime you try to print? Every third page?
2. Does it cure your problem?
3. What trouble does it cause?
I recently installed a D-Link router with Network Printer option.
To keep the printer from periodically winking off, D-Link customer support recommended that I disable the Windows Firewall feature.
It seems that this may cause more trouble than it cures. Is disabling the Firewall something I want to be without???
