Epson WiFi Printer won't work with new router

I recently changed my router and attempts to print result in "Printer Not found"

The Printers and Scanners window showed the printer as present. I tried Reset Printing and the printer disappeared. Add Printer brings up another window but finds nothing and I don't know how to populate it.

I printed a Status Sheet from the printer (Epson-2010WF) and it listed the SSID as the old router name. Further down the list of wireless info it listed the new router as SSID List, so it knows it's there. How do I persuade it to put the new router name as the SSID? Will that solve the problem?
