Just installed a Brother HL-2270DW Compact Laser Printer with Wireless Networking and Duplex on my WiFi network. For the time being, I have it connected via WiFi. I have tried several of the free iPad printing apps and none of them have worked properly. I am ready, willing and able to purchase an app but I am not willing to purchase one that isn't going to work! The printer works properly from my PC and my laptop. So..does anybody have the same setup and, if so, what app did you use to make it work??
