After a succesfully installation of a wireless printer, all tests OK, pinting an scanner, etc. after a few minutes, the MacBook have "trouble to connect with the printer"
I already install the Lexmark driver update.
I even verify the printer and is OK, It is responding to ping. etc.
I already try with other printer, installing everything ok, but the same, after a few minutes when I try something with them te MacBook can not conect with the printer none.
If I restart the MacBook, works again, but after some minutes, the problems back.
I made my tests with Lexmark, Dell and HP and it results in the same issue.
