Hi Lemuriano, could you add some details about your printer to h-node?
It would be nice if you could add relevant part of the output from sudo lsusb -v and the details about how to configure the printer to be usable through wireless.
Here's the link: http://h-node.org/printers/view/en/601/Hewlett-Packard-Deskjet-2050-J510
