Connection and installation

- Official hardware guide section 2-8: printer off, rear USB interface to computer, then printer on. Use a USB 2.0 data cable, not the USB memory host port; reconcile timing with actual installer prompts. Obtain compatible official KX package, extract and follow current instructions, select actual P5021cdn/USB. Express Install screenshots are legacy DVD examples, not a promise of identical current screens. Check actual queue/port/media/duplex and test.
- Ethernet: printer off, connect rear network port to approved network, then power on. Verify actual IP and same approved network.
