I went to google and inputed hp photosmart 1315 and vista this is what someone else did to make it work.
Thanks for the info on downloading the hp photosmart 3100 driver. My printer is back in business!
My 1315 thinks its a 3100 and works fine in Vista. (1)Disconnect printer from computer, (2)click "add new printer", (3)go to driver for HP Photosmart 3100 and install it(4)Connect printer to computer.
Anytime you have a problem like that google it and if your willing to read long enough you will in most cases find a fix.
The reason I posted what I did about the printer server was so if someone else has the problem and they google printer server windows 7 it will come to this post.
