Cannot communicate with the printer

I have a FIOS Quantum modem/router (dual-band) and a WCB3000N wifi range extender.

SSIDs:

2.4 GHz = Home

5 GHz = Home-5G

I have an HP Officejet Pro 8600 Plus - N911g which is 2.4 GHz ONLY (FWIW...IP address 192.168.1.154).

My Lenovo T430 and T440 Windows 10 laptops cannot "see" the printer on the Home SSID.  The laptop does NOT "see" the Home-5G SSID.

My iPhone 6 "sees" the printer (192.168.1.154) on the Home AND Home-5G SSIDs.

I have found many references to "cannot communicate with printer" on the web but none that provide a clear solution.  What my research is telling me is that the problem is a network issue of some kind.

Can anyone help?
