Trouble installing printer

I am having trouble installing printers on my Win 7 64bit system. This system has been up for a while and had the same printers I'm trying to install installed on it but they are network printers and I just switched routers. The system see the new work just fine. This is the only change to the system, a new router/network (same network new wireless connection).

I just get the window with the green bar searching for hardware forever, it never finds anything or takes me to the next step.:banghead:

Some ideas on what to do/look for please?

Thanks
