I have the Latest drivers from Brother for the HL 5340 Laser Printer for my Windows 7 Ultimate computer.
When I try to print to the Brother 5340 my computer turns off, then restarts. Everytime. It happens when I open the Brother Properties page and press send a "test page" to the printer.
The printer is not shared (on a network)
Also, I turned off the Brother, reinstalled the drivers, and when I turned the Brother on -- the computer crashed again!
