When connected to a network printer, I turned on the host guest user, and set on the printer, the result is not connected to the host, in the "Advanced sharing settings" turned off the "password protected sharing", can be closed after saving and then open, or did not close successfully.

Originally, is the problem of guest, the solution is to set the password of the guest to empty.

Recent time, some busy, some trance, to calm down, down to the line.
