Thanx everyone for the inputs

I finally bought liteon cdwriter (the salesman evry efficiently convinced me to do so !

).
Now i hav 4 options for the printer. Please decide for me.
1) Lexmark Z-615 . (this model the salesman suggested strongly saying it has excellent support & decent print .. but i donno nethin abt lexmark !)
2) canon pixima ip1000
3) Hp Deskjet 3745.
4)HP Deskjet 3845.
Now i will use the printer rarely so need but i will for important print out also so dont really want to compromise that much with print quality at the same time.
ONE BIG CONFUSION : I have a old mercury motheboard ( KOB P4 M266 NDFSMx). I think it supports usb1 only.
now some of the above printers described to use usb2 port ... im not clear abt those .... will i be able to attach those to my machine?
Please help me out again
