After my last update, my MacBook Air doesn't recognize my printers

Hi,

Would it be correct to assume that your printers are AirPrint-enabled models (in the list in About AirPrint - Apple Support), and that they were working well wirelessly with the MacBook Air before the update in question?

If other printers, please post back with the exact models. Also, are you using macOS 10.12 Sierra (this area of the communities), or possibly another operating system version?

The AirPrint technology allows printing without having to install additional drivers, provided that a printer and a computer are connected to the same network (router).

If applicable, and if all settings are OK, try the following procedure:

Power off the Wi-Fi router, the printers, the MacBook Air, and all other devices/computers. Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printers. Wait a minute or two. Power on the MacBook Air. Finally, power on all other devices/computers.

Add a printer to your printer list so you can use it on Mac – Apple Support (UK)

Hi,

Your printers and/or their software is probably too old for the newer OS. At some point all hardware becomes incompatible with a newer OS. You can try to find if someone created newer software for your printers by doing an online search for your printer model and software for it and the OS you're now running.

If your printer is not compatible with Apples Air Print. Which does not require a print drive. And you printers support has no updated drivers for your new operating system. And deleting and re-adding the printer doesn't help An online search is all thats left.

Have you tried deleting and re-adding your printers. The link that you got from Jan should help. But you still should read the documentation that came with the printers. Or look it up online. You do not say what model printer.https://www.lifewire.com/reset-mac-printing-system-to-fix-os-x-printer-problems-2259970
