My Big Sur macbook cannot communicate with my hp printer

Hi,

The HP Envy 4527 All-in-One Printer is mentioned in About AirPrint - Apple Support as a model supporting the driverless AirPrint technology. This means that it should work without additional drivers from the printer manufacturer, providing that the printer and the computer are connected to the same network (Wi-Fi router). Would it be correct to assume that you want to add the Envy 4527 as an AirPrint printer?

Have you tried to reset the printing system?

Reset the Mac printing system to solve a problem - Apple Support

To begin with, if everything is properly configured, you may want to test the following procedure: Power off the router, the printer, the computers, and all other devices (iPhones, et cetera). Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printer. Wait a minute or two. Power on all computers. Finally, power on all other devices. Any change?

Try this potential quick fix:

1 - go to the System/Printers & Scanners preference pane and remove your printer.

2 - close and reopen System Preferences.

3 - add your printer back with AirPrint as the connectivity.

If that doesn't work follow Jan's more detailed procedure (if you already haven't done so by the time you see this).

Hello again,

A remote diagnosis is always difficult, especially when three devices (printer, router, and computer) are involved. Is there anything special with the Wi-Fi system/router? Anything with 2.4 GHz /5 GHz or other router settings that could, somehow, affect the communication between these three devices only? I assume that you have tried another restart of just the computer.

Thank you for the information. The reason for mentioning 2.4 GHz/5 GHz is that there have been reports in some other cases about difficulties with an automatic detection of devices and selection of bands. This could possibly lead to, at least temporarily, disconnected devices. If applicable (I do not know anything about the Sky routers), one could choose a manual 2.4 GHz router setting (and switch off 5 GHz), just for a test. According to the specifications (https://support.hp.com/us-en/product/hp-envy-4520-all-in-one-printer-series/5447920/model/11534751/document/c04704159), the Envy printer in question is 2.4 GHz only. On the other hand, you have not had any issues with the Catalina computers . . .

Good.

When going through the entire power cycling procedure, the power-on order, (router->printer->computer) as described earlier, can be important.

For now, you will just have to wait and see.

Yes, if necessary, you could carry out a comparative test with an old router. You should not really have to connect this router to the Internet. The interesting part is the local network (the wireless LAN), not the WAN. It should be possible to set up a separate local Wi-Fi network on the old router, and run tests. If you post the new and old router models (not serial numbers or codes), I could try to find any available documentation.

You're welcome! Good news. Glad to hear that it worked.

Kind regards,

Jan

Thank you. Good to hear that it is working. Do not hesitate to post back, if necessary.
