I purchased a wf-3640 and tried to connect it to my Samsung Tab4. I had problems and called their 866-925-4874 support line. They immediately told me that I would have to pay $250 to have one of their technicians take care of the problem for me. I was shocked that they couldn't walk me through the process. I spoke to a supervisor and he told me the same thing. I told him that I paid $110 for the printer and that to pay an additional $250 for asking for help to set it up; is call a shake-down. He told me "Take it or leave it, it doesn't matter to me". I will be returning the printer.
