Comcast Xfinity XB7 Gateway w/ wireless printer

I just upgraded from a Comcast/Xfinity XB6 to an XB7 and since then I found that my staticly assigned IP wireless printer is no longer working. I think there's a problem with routing, masking, firewall, etc. The printer is an old HP Deskjet 3050 aka J610. I'm trying to print from multiple devices. I'm trying everything but any suggestions would be appreciated. I've verified connections, dhcp and IPs of all devices. There are management interfaces from xfinity.comcast.net (which they seem to prefer I use) and 10.0.0.1 which look almost identical to the xb6 interfaces I'm used to. I'll look for
