I have found that I needed to install gs-esp, now I can use the escp2-400.ppd file vith the resolution of 360*120dpi. However there are also some troubles:
1) the intermediate resolution of 360*240dpi specified in the options prints a lot of white papers.
2) the resolution of 360*120dpi works, however with respect to the same resolution mode of the windows driver, there are more intermediate white lines.
3) I haven't found in the driver an option that allow the high speed printing system, i.e. the bidirectional mode( as allowed in the windows driver) that allow to print the page in half time.

Thank you for any suggestion,
