HP Laserjet 4240n Q7785A

The LJ4240n is fast A4 mono laser printers intended for workgroups or individuals who need a really fast printer. The LJ4240n runs at up to 40 pages per minute. Output quality is high with a resolution of 1200 dpi at full engine speed.

The fast built in network connection, processor and memory offload tasks from user computers quickly. The LJ4240n has a 460MHz processor, matched by 64MB of memory giving the machine's speed.

The printer is based on the LJ4200 / 4300 series and has a range of optional trays, a duplex unit, envelope feeder and stacker / stapler - it uses the "B" variants of those parts.

The LJ4240n adds a USB port to its predecessors IEEE 1284 parallel port making it easier to connect directly to recent computers. Unlike its predecessors the LJ4240 JetDirect is an embedded device so it always ships network ready.

The LJ4240N takes a slightly smaller 10,000 page cartridge than either the LJ4200 or or LJ4300 and has a (pointlessly ?) different fuser.

The LJ4240 is an update on the LJ4200. Its faster than the 4200 but slower than the 4300 despite having a faster processor. It takes the "B " version of the accessories. It has all the language and network support features. It ships with network and USB ports.
