Clear any reference to old router on wireless network for printer set up

I have a remote network that consists of 4 Windows 10 workstations [3 at 1909, and one at 1809].  They have recently changed ISP providers,  and all 4 workstations have connected to the new router wireless.  The issue is with a printer.  It is a Canon MF733CDW.  It is connected to the router, and two of the computers are connected and and working normally.

The other two computers will not connect and print with a wireless connection.  When I run the Canon install file, the Canon software cannot find the printer even when I put the printer IP address in.  I can log onto the printer with the one workstation via the printer web page, and all looks normal.  When I try connect the printer via Windows 10, Windows 10 finds the printer and installs it, but the test page will not print.  It sits in the queue forever, but does not print.  I have tried sharing the printer from one of the workstations that does print.  The workstation finds the printer, but again will not print a test page.

I have reset the network adapter from within Windows 10 with the same results.

I suspect there is some confusion in the workstation because of the change of routers, but have not found a method to clear any remainder of the old router connections.  I am leary to do a winsock reset, as I will probably loose the connection.
