I recently purchased a Brother Laser printer for $70 on Amazon and have a few questions, if anyone who has a similar printer can answer them please do: 1) There are negative reviews claiming the wireless functions are hard to set up, esp. with Yosemite (although they did upgrade their drivers for this printer). Are they? 2) Is the "deep sleep" function really an issue that should be considered a problem? 3) Is it generally acceptable to add a wireless printer to your dorm's wifi if you know the password (which we all have)?
