The E82670dn is the top of HP's E826 series. The E82650dn runs at 50 ppm and 26 A3 cpm, the E82660dn at 60 and 30, and this model at 70 and 35. Memory, storage, processor, paper handling, media range, finishing and security are identical across all three, so the choice is purely about throughput and power.

Power scales with speed: approximately 1,090 W printing here against 1,010 W and 870 W on the slower models, all idling at 36 W. Noise does too, at 7.6 Bel(A) against 7.5 and 7.4.

The caution on this model is sharper than on its siblings. At 70 ppm the print engine substantially outruns the dn feeder, which scans at 90 ipm simplex. If the office scans as hard as it prints, HP's Flow configuration with its 300-sheet feeder at 150 ipm simplex and 300 ipm duplex is the correct build, and we will quote it alongside rather than let a scanning bottleneck undermine a fast printer.

A note on the Managed range: HP's LaserJet Managed devices are built for contract and managed print environments, and their cartridges carry Managed part codes supplied through that channel rather than off the retail shelf. Confirm with us how consumables will be supplied before ordering, because it changes the running-cost picture.

The E82670dn suits central print rooms and reprographics functions where printing is close to continuous through the working day: large corporate offices, universities, hospitals, government departments, and any operation producing long collated and stapled runs against deadlines.

Buy it when queueing at the machine has a measurable cost in staff time, because that is the only thing the extra speed purchases. If the machine will be idle for stretches of the day, the E82650dn does identical work with the same interface, the same consumables and the same service story, for less capital and less power.
