Hello,
I am having the same problem as the users above, where I am able to install my HP Deskjet 450 (C8111A) but when I attempt to print a test page (or anything else) it just errors out.
I have Windows .81 64-bit, and only have the blue/3.0 USB ports on my computer. What can I do to make the printer work? It is the printer or the cable?
