Mauro, can you follow the instructions of the section "CUPS error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems. Please boot your system (or restart avahi-daemon and cups manually, avahi-daemon first) and check whether your printers get broadcasted using avahi-discover. Now restart avahi-daemon and check whether this makes the broadcasting of your printers stop. After that attach the CUPS error_log.
Always attach files one by one and uncompressed, not packed together. This way one can quickly look into the files directly out of the browser.
