Regarding the dark printing, try an updated printer driver, or another printer driver. Regarding printing from DOS, I am sad to tell you that I don't remember all the details, I abandoned DOS during the previuos millenium. :-)
>The printing is very dark and it is taking too much time only in test page printing. From my dos application nothing is coming. One more thing, where I define this Dos Option print unlike window-98.
