Wi-Fi Printer No Longer Prints Now That I'm Using Xfinity WiFi Service

I've never had a problem before with this printer communicating with my laptop through Wi-Fi to print (HP98553E - HP OfficeJet Pro 6960).  I just switched over Internet services to Xfinity and now my Wi-Fi printer no longer prints by way of wireless communication.  I had to hard-wire the laptop to the printer for it to print this morning.  Wireless print requests to the printer just sit in the printer queue, and the printer states it's offline.  It's not.  I haven't seen anywhere in the printer device setup where it states a specific Network name... but I'm wondering if that's related to the printing problem...  It seems the Wi-Fi printer doesn't recognize the new network established with Xfinity hardware.  The Xfinity modem is fine, Wi-Fi services through the modem is working just fine for my laptop (which is currently working wireless to the Internet).   How do I fix this problem?
