产品名称: Samsung Xpress SL-C480 Color Laser Multifunction Printer series
操作系统: macOS 10.14 Mojave
My Samsung C480W print also have problem after install Mojave, it cannot use the manual double sided print any more. I try all reset print system, reinstall printe, delete printer driver. It only allow to install the AirPrint driver rather than to network drive. The double sided print function become grey in AirPrint.
airprint is a simple and fast way to print.not support all printing function .if you need duplex printing , It is recommended to choose a computer driver for printing.or install HP smart print app to print.
Mac 10.14 is a new OS, It is recommended that the software update function be used to update the driver to install.
