Hi all. I've been struggling with this issue for a couple months, without success. About my system: Dell PC, Vista 32, SP2, using a Brother MFC 490 all in one that is connected to my network wirelessly.
My problem is this: a couple months ago, I noticed that the desktop refused to enter standby, instead showing a popup that stated, "the device driver for the WSD print device is preventing the machine from entering standby." This is annoying at minimum, a waste of money and system life at worst.
I've tried the following without success: restored the system to a point prior to the issue, updated the wsd driver, unistalled/reinstalled the wsd driver & device, uninstalled the Brother software (the printer remained on the system, thanks to auto detect), and banged my head with great enthusiasm on the keyboard.
Hopefully, there's a relatively easy fix! Thanks for any suggestions...
