I am trying to install a hp psc 2175 all-in-one printer on my Windows 7 computer. When I plug up the printer windows detects the printer an installs the icon but I can see that it did not install the psc 2175 drivers. HP doc states the print drivers are in the win 7 OS. If I check the the printers list in win 7 I cannot not find the drivers. The csan feature works but the printer is not listed when I try to print from word.
