No. It doesn't. As I go to Preferences -> Printer Configuration then (on the CUPS page) Administration -> Manage Printers then choose my printer and (on printer page) I press Administration button and from the drop-down menu I choose "Set As Server Defaults" everything is fine for the current session. After restarting I have to repeat the procedure.
Anyhow the success is the printer is usable, and the firmware is loaded at the system booting (the printer must be "on"). That is great!
It would be nice to set it as Default Printer, but... maybe later on I'll try to do it.
