I have an old plotter, HP Designjet 450C, that's currently hooked up and functioning well on an older desktop. I recently purchased a new desktop, and was wanting to install the printer on the new desktop, only I've long since lost the installation CD for the printer, and HP no longer offers support for the 450C. Is there any way I can make this work using what I already have on the old desktop? Thanks. Printer sharing is not really an option as I plan on getting rid of the old desktop as soon as I get this figured out.
