I have looked around depending on what driver I have to use, the lowest
is 300 x 300 dpi

Maybe I'll have to save my pennies to get a different printer, but for
my case is very difficult because I live in a nursing home. I'm not
complaining, but I just wanted to note my budget. :)
Maybe if I play around with the settings, I may get it right since when
I use to use mandriva, it printed just fine for everything, but now I'm
using kubuntu and I did notice when booting, it was loading a HP linux
print and image system. But I now need to investigate into this more.
P.S. thanks for the info you gave me to help figure things out.
