MacBook Pro stopped communicating with printer

An AirPrint-supported printer would be needed for printing without additional drivers. However, a Samsung CLP-680DW is not listed in About AirPrint - Apple Support (en-us August 21, 2024) as a supported model. On the other hand, AirPrint is mentioned in the specifications (under Mobile printing capability) at https://support.hp.com/us-en/product/product-specs/samsung-clp-680-color-laser-printer-series/model/16462334 (this may be an early firmware/AirPrint version, though).

If the printer actually supports AirPrint, it must be connected to the same network (Wi-Fi router) as the Mac. AirPrint works with wireless (Wi-Fi) or wired (Ethernet) network connections, so it may be worth testing to wire the printer to one of the LAN ports of the router instead.

If there is a problem with AirPrint, try a full power-cycle sequence (including the router, the printer and the Mac).

If the printer does not support AirPrint, compatible drivers would be needed. Unfortunately, CPL-680DW drivers from HP (Samsung printers are now part of HP) appear to be available for up to macOS 10.14 Mojave only.

PCL6 and PS3 are mentioned under Print languages in the specifications for the CPL-680DW, so a workaround could possibly be to try generic PCL or postscript drivers under macOS.

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

First delete the printer from the list of available printers.

Then use the Option key while clicking on the plus sign button to add it back. That forces it to open the open source driver for the printer.

I don't have Ventura or Sonoma.

Can you show me the settings you have for printer settings please with a screen shot?
