printer certficate expired E525w

I updated Macbook pro and now my E525w printer paused "certificate expired"  When I go into printer on my Mac to "Show printer web page"  I am unable to access web page....Instead I'm unable to open.  DNS_Probe_Finished_NXDOMAIN  

I've tried typing the printer's IP address into the url bar and get nothing....

Help? How do I get rid of the "printer certificate expired" message?  Please use layman's terms....I am not "techy." Thank you!
