I have a brother HL-2170W wireless printer.. it has been working perfectly fine with windows 7, when i first set up the printer with the main computer in my basement, all i had to do with this computer in my bedroom was to go to add a device-> printer-> search for printer and it would find it automatically. Couple days ago it just suddenly stopped working, under devices and printers, it was there but grayed out, i switched the "send to onenote" as the default so then i could switch back to the brother printer thinking it may do something, instead it gave me error code 0x00000709. I searched this in google, however i did not come across any solid answer or resolution. I took out my laptop (has windows 7), which did not have the printer already on it.. went into add devices->printer->search for wireless/bluetooth printer-> bam in about 5-10 seconds it came up. I still cant understand why my PC is not seeing it?? So far i have only tried using CCleaner to clean up the registry, but this did not solve the issue. also, please dont tell me to download drivers, because my laptop had NO drivers installed (other than the default windows) and it found the printer just fine. Also, this PC found it just fine when i first set it up without any drivers needed.
