Please do the following in this order: 

·Uninstall all Sammy software, put in the Trash and empty the Trash.

·Please reset the printing system per Reset the Mac printing system to solve a problem

·Next, follow the instructions in Adding a printer

Hi,

Also, the Samsung Xpress M2885FW is mentioned in About AirPrint - Apple Support as a model supporting the driverless AirPrint technology, so a printer driver should not be required (when using a network connection).

Drivers/software from the printer manufacturer may or may not add functionality. There is a (Feb 11, 2021) Big Sur driver (https://ftp.hp.com/pub/softlib/software13/printers/SS/Print_Common_SW/Samsung_Mac_Driver_V3.93.01.dmg) available via the M2885FW support page (https://support.hp.com/us-en/drivers/selfservice/samsung-xpress-sl-m2885-laser-multifunction-printer-series/16462721/model/16462723).
