I am running xp2000 on Fujitsu s6000 notebook processor 1600 mhz 504 ram and it has plenty of memory. I got a lexmark 5600 printer and installed the software, somehow it got messed up so bad even after I removed it so I had to use system restore. Maybe I did something wrong. I got my computer running fine now and would like to try again. Please tell me the correct way to install this.
