Thank you! I would like to try it on July when I got more free time.
Besides, now I am thinking people's suggestions are making good sense,
probably it's right the print servre would not be faster after upgraded
to 64-bit, because I took a glance into gutenprint source, the very part
of eventone dithering (which from my limited knowledge is what computer
busy doing for the printer) is about 700 lines of C source code, most
variables are defined integer, which seems would not benifit from 64-bit
processing. I would like to try 64-bit anyway.

Thank you for all the help.
