Win 7 error 0x000000709

Major problem printing to network (peer-to-peer) Brother HL-3040CN. With their techs have deleted and added new device several times and updated firmware. However, following successful install and printing, on warm reboot, printer is grayed out. The most recent time I got the error code. I checked for this error on line, but can't find solution for Win7. BTW, I have also run the Simplix updates, though have not run a Win 7 re-install. Help please. Thanks.

Hi

i take it warm reboot is either Hibernation/sleep, and the printer is available from a clean start,
if the above is true then its likely a power option setting

Check the Printer power management tab in drivers ---- turn OFF let the comp put it to sleep

are you using a seperate Wifi device -- if so how is it attached, or the onboard card
if your using a hub you'll need to check its power option setup as well

Running Restoro fixed the problem. I wrote asking how I could make a donation cause you've all been so good to me, but have not heard back. Could you refer me to whomever? Thanks.
