better about the experimenting with something I don't print with much. Actually
I have a 1200 DPI older laser in the attic too, got it for $5 at the local
hamfest since it was so heavy and gives an error code. Never even really looked
at it though, only got it because I know the drums cost hundreds for it, but
never sold it off. Time to take a look I think..
