HP LaserJet Pro 400 Color M451DN laser printer with toner bundle

Small-office colour laser with toner bundle

This HP LaserJet Pro 400 Color M451DN is a network-ready colour laser printer supplied with a full set of generic toner cartridges. It prints black and colour at up to 21 pages per minute and offers automatic duplex printing. The 300-sheet input tray suits modest daily volumes. Ethernet connectivity lets multiple users share the device without a host PC.

Sustained output at rated speed

Both mono and colour throughput hold at 21 ppm once the engine is warmed up, so longer print runs do not slow down after the first few pages. The 600 x 600 dpi resolution remains consistent across extended jobs. Duplex printing runs at the same rated speed without a separate simplex-to-duplex penalty. The included toner set provides 4000 black pages and 2600 pages per colour cartridge.

Check your network and paper handling

Verify that your router or switch has a free RJ-45 port for the Ethernet 10/100Base-TX connection. Ensure the 300-sheet tray capacity matches your typical refill interval; heavier environments will need more frequent loading. Confirm that your print server or driver environment supports PCL or PostScript emulation for this model. The unit may show cosmetic discoloration from prior use.
