I have never used the printer on the windows and the Mac side at the same time, yet I still get the constant reloading of the unwanted laserjet driver. I clicked devices in the menu and clicked disconnect all and I still get it.
It many be a default but it is dumb! It won't for example let me tell my Canon mp980 to use the rear tray. The Canon driver is needed and works well under parallels so why clutter up the drivers folder with the unnecessary one. There should be an option to not install the Laserjet 2800.
