NO .inf file

I downloaded an older driver for a Panasonic KXP-1124. I need to use the older driver with XP to obtain custom paper size for printing individual tractor feed labels. The XP driver does not allow custom size. I print (1) label, and an entire page of labels advance.
The question is. There is no .inf file in the download. When i attempt to change the driver XP expects to see an .inf file for installation. How can i get passed this? or is there an .inf file somewhere?
thank you very much for your assistance.
