Orbi RBS50 won't play nice with my printer, can I add a Netgear AP to help?

Mesh is a RBK52.  Printer is a Epson WF-7840.

Already did the Channel 11 and changed CTS/RTS to 2347.

Printer connects, but connection speed is 2mbps.  

Can I add a RBS10 as a satelllite or repeater? If not, can I add a access point like a WAC104 so I can physically connect from AP to Printer?

Old eero mesh had no problem with this printer before, so doubt it's the printer.

Orbi AC series are not wirelessly compatible with AX systems. You can ethernet connect RBS to the AX system and would work that way:
