I currently have a IBM Pentium II computer with 256mb ram. I want to order a new Canon IP6600D printer. Will my computer be able to run the printer? Also my computer does not have any USB ports. The salesman said all I need to do is order a USB card and install it in one of the slots. My other question is this, I don't have a lot of computer skills but I have been inside and added memory. Can I do this upgrade? Is it a simple as plugging it in the slot or is there more to it? Thanks again for the help!
