You are trying to use the printer on your router via the IPP mode of the router. It is possible that this mode is not 100% compatible with the CUPS backend. Does the router provide other access modes for the printer, like for example TCP/Socket (Hp JetDirect) or LPD? The easiest is probably to make it working via TCP/Socket. Look into the confioguration web interface of the router (http://192.168.1.1/ with a web browser) and activate the TCP/Socket and/or LPD protocol. Then try socket://192.168.1.1:9100 or lpd://192.168.1.1 as device URI for your CUPS print queue (If the router supports SNMP, possible URIs can be auto-detected by "/usr/lib/cups/backend-available/snmp 192.168.1.1"). Does this work?
