Download Missing Update.inf File

I have recent;y set up my new Win 7 PC, and re-installed my old printer ( which used to run on my old XP machine ), so far so good. Printer works on my new PC. I set up my old PC in another room for my daughter, and set up a home network. I have set theEpson printer on my PC to share, and can see this printer from my old pc, through the network. THe problem comes when I try to set this printer as my default printer. On my old pc, it tells me that I do not have the required driver file on my server to connectto the shared printer, and prompts me for an INF file, which I undertand is a windows information prompt file. How and where do I locate this file, so my old computer can print to the shared printer through the netowrk?
