Wireless colour laser for small offices

The HP LaserJet Pro 400 Color M451NW is a wireless colour laser printer built for small offices and workgroups. It prints black and colour pages at up to 21 ppm with a 600 x 600 dpi resolution. A 300-sheet input tray supports moderate daily volumes without frequent refills.

Replacing inkjets or single-function lasers

This model replaces slower inkjet printers or single-function monochrome lasers when colour output and network sharing are needed. The jump is worth it if you need consistent 21 ppm colour speed and Wi-Fi connectivity for multiple users. It is not for buyers who need automatic duplex printing or higher monthly duty cycles.

300-sheet capacity handles typical department loads

The 300-sheet tray comfortably handles daily printing for a small team producing dozens of colour documents. It runs out when workloads exceed the tray capacity or when heavier media support is required. The unit ships without toner cartridges.

Questions about this item

What clearance is needed around the M451NW for its 300-sheet input tray to open fully?

The printer holds 300 sheets in its input tray; allow enough space at the front for the tray to pull out completely and at the rear for ventilation.

Which step is most often missed when connecting the M451NW to a wireless network?

After powering on, use the control panel to select the SSID and enter the password; skipping the on-printer network setup leaves the printer offline.

Which consumable will need replacement first on the M451NW if toner is not included?

The unit ships without toner, so the four cartridges — black, cyan, magenta and yellow — must be installed before the first page prints.
