Hmmm ... version 4.00 seems a bit strange, not sure that's what we're looking for.
Can you try the following please:
To determine which printer driver a printer uses, use Start -> Printers and Faxes then right-click the printer, and choose Properties from the pop-up menu.
Next, click the Device Settings tab, right-click the installed printer name at the top of the list of device settings, and click About.
Can you make a note of everything that comes up in the About window, and post here please - that may give us more to go on!
