they do not give Linux support. they have a driver but do not give a linux support. i have to look meself.

i can choose now more thins like high, normal, economy quality and 600, 1200 and 2400 dpi but the print result is the same.
the printer print very fast and in a normal quality.
normally the printer has to print longer when i choose 2400 dpi and high quality.
i do not know why is it so.

That is probably because the printer IS printing with more Dots per Inch - thus slower, but maybe the source material, or the file format, is not good for such high quality printing?
If it is text, there is no reason to waste ink, though I don't know what might help with quality improvement there.
if it is image related, then it might be the type of image format being used, or what the program you are using is capable of sending to the printer. You may have to see if the application has settings for image quality,
