Obrati paznju sto je obiljezeno crvenim.
Tu trebas upisati ime tvog printera iz tabele sa podacima iz predhodnog koda.
Onaj kod ti nece vise trebati.
Bar ne za ovo sto ti treba pa ga mozes i skloniti. Bio je samo zbog toga da ti da pravo ime printera.
Podrska samo putem foruma, jer samo tako i ostali imaju koristi od toga.
