HP LaserJet 4240N Network Laser Printer

The HP LaserJet 4240N is a monochrome laser printer built for shared office use. It prints up to 40 pages per minute at 1200 x 1200 dpi resolution. A 500-sheet input tray supports longer runs without reloading. Ethernet connectivity allows direct network attachment for multiple users.

Small teams needing fast black-and-white output

This printer suits workgroups that need reliable, high-volume mono printing over a wired network. It does not print in colour, so buyers who need colour documents should look elsewhere. The unit ships without toner, so a cartridge must be sourced separately. Wireless or USB-only users will need a different model.

Ethernet RJ-45 network interface

The single specification that decides fit is the Ethernet RJ-45 port. If your environment requires Wi-Fi, USB direct printing or a parallel connection, this unit will not integrate without extra hardware. The wired network port is the only built-in data interface provided.

Questions about this item

How loud or hot does the LaserJet 4240N get when printing at 40 ppm all day?

The unit was fully cleaned inside and out with worn parts replaced, including the fuser film and pressure roller, so it runs at normal operating temperature and noise for a 40 ppm mono laser.

What cables or network gear must I already have to use the Ethernet port on the Q7785A?

A standard RJ-45 patch cable and a wired network switch or router are needed; the printer ships with power and network cables where applicable.

Will the 1200 x 1200 dpi output and 500-sheet tray work with my older HP LaserJet drivers and paper stock?

The 4240N supports standard PCL and PostScript drivers available from the manufacturer, and the 500-sheet input handles the same paper sizes as earlier LaserJet models.
