I have a ZT desktop PC running Windows 7 64-bit on a home wireless network. My printer is a Brother HL-1400 laser monochrome, connected to my PC via USB. About 9 months ago I bought my wife an Acer laptop, (Costco), also Windows 7 64-bit, and was able to add it to my network so it would print wirelessly. About 3 months ago, it would not print, but since most of the printing is done through my PC, I did not immediately look into the problem. Well, my wife would like to again be able to print wirelessly, so I checked all my settings and followed the instructions as I did initially, but I've had no luck getting printing done wirelessly from the laptop. When the print command is given, the printer does not wake, and the print jobs stay in the queue, with no error message on the laptop. System Restore does not offer a restore point far back enough to when the printing worked. It works perfectly when connected via USB. I called Brother, and after they verified the printer was OK, they would not help me further, saying it's a computer problem. I then spent over an hour with Costco concierge service, and they had me reload the printer drivers, but this made no difference. I called Acer, and through remote connect they said that there was a problem with internal conflicts in the laptop, and could help only if I paid about $80 for them to fix this one problem, or about $300 for 2 years. I would very much appreciate if anyone could point me in the right direction so I can again print wirelessly.
