Hi all. We have a HP psc 1315xi that will print color, but not black!!! Very strange. The printer is new and worked with our old Emachines computer and my laptop. We just hooked it up with our new computer. It won't print with my laptop either. I tried reinstalling the software once, and I can't do that anymore since I lost the CD! Color, but no black?!?!?!? HELP PLEASE!!?!?!??!?!?!!?!???!!
