Ethernet is supported in the cited model data. Use the printer's own RJ45 port for a direct network setup; sharing a USB printer from a PC is a separate route.
Wireless networking is supported. Check the printer's exact setup menu and the router settings before changing saved network configuration.
Scanning is a separate function from printing. If printing works but scanning does not, install or select the exact model's official scan software.

- Check the full model label, including any suffix.
- Select the correct Windows architecture or macOS version on the manufacturer site.
- Choose the package whose description matches printing or scanning needs.
