Predvčerom som si reinštaloval Windows a keď som nainštaloval tlačiareň (HP P1005), zistil som, že tlačí stránky celé čierne + na niektorých miestach pásy atď. Čím to môže byť? Toneru tam je asi 2%, ovládače sú z originálneho CD a predtým fungovali (ani opakované odinštalovanie a nainštalovanie nepomohlo).

The terms LF, MF, and HF refer to low, medium, and high frequency, respectively. Clearly, when the names were assigned, nobody expected to go above 10 MHz, so the higher bands were later named the Very, Ultra, Super, Extremely, and Tremendously High Frequency bands. Beyond that there are no names, but Incredibly, Astonishingly, and Prodigiously high frequency (IHF, AHF, and PHF) would sound nice.
