I've just taken delivery of a Riso SC5500 rip to replace the SC3000 I've been using with my GR3770. I've been using an old but reliable laptop with Windows XP on it but I can't seem to get the drivers to work. I found a workaround about installing a PPD file from the Windows NT driver on the laptop instead but I can't seem to find that PPD anywhere amongst the driver cd that came with the rip. Can anyone share that PPD with me? Or is there an easier workaround I can use?
