Orbi 371 system: mac can't connect to printer

What is the size of your home? Sq Ft?

What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.

Is the printer wireless or ethernet connected to the Orbi system? Ethernet would be recommended.

 My MacBook Pro has no issues connecting to the Canon MFP660 series printer and printing. My wife's MacBook Air has terrible trouble using the printer. It frequently can't connect. What used to work is deleting the printer from her mac and re-adding it. Then it would work for awhile. Now it doesn't. I can see the printer using bonjour, but when I go to add it it says it can't connect to the printer. I tried pinging the printer from her mac. Timeout every time. No problem pinging from my computer. Both macs on the same wireless band (5 GHz); the printer is on 2.4 GHz. The printer is currently connected to the satellite.
