I just got a new Galaxy s5 on Thursday and since then have been trying to pair my phone with a Lexmark printer. I have used the on-line manual, bought a new book called "My Samsung Galaxy s5", and even called tech support. Tech support said I have to call Lexmark. I was able to print a test using an app called PrintBot, but PrintBot charges per print. This did prove to me that it CAN print. Any suggestions?
