*** This bug has been marked as a duplicate of bug 326289 ***
Hello, I effectively had two duplicated print jobs when I run lpstat -R. After running cancel -x -a (as suggested in comment 58) everything works fine again. I remember having installed a new printer (Epson ET-3750) with a Wi-Fi connection and having some trouble with the printing of the first documents. Thanks for your help!
