Note: For you parents who have no clue how to work the internet. DO NOT TOUCH THAT ***. My mom called tech support for her printer- ended up changing out IP address and *** up our DNS server.
dns should be set to automatic...
unless you are using a private dns
I said it before and I'll say it again, IUE!
if she still can't print, unplug the printer, leave it off, restart the computer.
Turn it back on, reinstall the printer, restart again, and then try to print.
Pretty much covers everything and is simple for people who don't know what they're doing to get it to work.
If you could look at the ip the router is giving the printer I'd say to open command and ping it, if it pings then it's a software conflict, or the printer is bad.
