I have installed my new printer (Epson RX560) into my macbook, it is already in my PC. The printer appears on the desktop (Mac) . When I went to print a document it did not recognise it or any other as this is a new book. Do I drag it into applications, to enable it to work, is this not the norm when you install anything into mac, I have installed a couple of small items and dragged them into applications but am still left with them on the desktop what am I suppose to do the them,do I drag them into the litter bin?
