Why is my MacBook Air unable to detect HP Color LaserJet MFP M277DW for wireless printing?

HP is inconsistent about whether this printer has AirPrint support with the online specs omitting that feature, and another HP AirPrint listing including it. The specs aren’t all that great, unfortunately.

Is the 20220111 firmware loaded into this printer? If not, load that, and test the AirPrint path again.

If that firmware is loaded and is not working, reset the network on the printer, re-connect the printer to Wi-Fi, and try again.

AirPrint avoids needing piles of HP add-on stuff doing who-knows what. It is usually preferable to vendor drivers.

You can try resetting your Mac's printer system.

I know this printer is successfully connected to wireless because another Windows computer here can print wirelessly.

Without intending offense, if that mattered, would we be here, discussing printing problems?

Whether Windows was using ad-hoc too? Donno.

As Tesserax mentions, this is all best connected to your Wi-Fi network.

The firmware release notes indicate network fixes, and iOS printing fixes, security fixes, and other fixes.

Getting that firmware loaded is preferable to having to troubleshoot those same problems anew.

I could not load the firmware: my Mac told me the software needed to be updated.

Load the firmware either from the printer (page 93), or from the Windows system, then.

Ah, that's the issue! Your wireless printer must be on the same wireless network as your computer. Did you not configure it originally to connect to your local Wi-Fi network?

Check with your printer's user manual on how you go about configuring it to connect to your Wi-Fi network.

I did a quick review of the HP Support site for this particular printer model, and I didn't see anything that says that this printer is AirPrint capable ... only HP's ePrint.

There driver support page is located here: https://support.hp.com/us-en/drivers/hp-color-laserjet-pro-mfp-m277-series/model/7089949?sku=B3Q11A

Ok, but you still have what appears to be two separate Wi-Fi networks. Unless that is a network requirement for you, you should only need to have a single network that is provided by your wireless router. This would be the network all of your wireless devices would connect to. No network switching would be needed.
