HP LaserJet Pro M404dn

HP claims the LaserJet Pro M404dn can print 40 pages per minute (ppm). In single-sided printing tests, it achieved faster speeds than that spec. Using a Core i5 test PC over Ethernet, the M404dn clocked speeds reached 42.3 ppm on a 12-page Word doc. On mixed documents including Excel, PowerPoint, and Acrobat files, it achieved an overall simplex speed of 22.1 ppm across testing. This edged out competitor models like the Canon LBP226dw by 0.5 ppm and exceeded the Lexmark B2236dw and Epson WF-M5299 by about 6 ppm. Out of the group, the LaserJet Pro M404dn proved the fastest printer, surpassing its 40 ppm rating during substantial document testing. Real-world speeds aligned with HP’s promises, validating the productivity potential of this crisp monochrome laser printer.

Setting Up the HP LaserJet Pro M404dn printer

Setting up the M404dn is a straightforward process whether you choose wired Ethernet, wireless Wi-Fi, or USB connectivity methods.

Here is an overview of the setup steps:

  • The input paper tray, priority feed slot, and output bin will need to be pulled out and extended on the printer. Adjust width guides in the input tray to match the size of the paper you loaded.
  • Examine the touchscreen display for any prompts to install the toner cartridge if it is not inserted. Follow instructions to pull the release lever and completely insert the cartridge.
  • For wireless networks, navigate on the touch display to the wireless menu and choose your network SSID when it is discovered. Enter the correct network password to connect.
  • For Ethernet networks, connect one end of an Ethernet cable to the printer port and connect the other end to your network connection source.
  • For USB connections, connect a USB cable between the computer and printer and follow the prompts on either device.
  • Install any required software drivers and packages from the HP website specific to your operating system for full functionality. Select the M404dn model during this process.
  • Send a test print job from your connected computer to the M404dn printer to validate the proper setup.
