Genuine OEM HP Color LaserJet Enterprise M855dn Printer Toners
The M855dn uses HP 826A toner and separate HP 828A imaging drums. Both come in four-color sets, but they do different jobs: toner supplies the powder, while the drums form the images. A drum set isn't another capacity choice for toner.
Toner Buzz carries the genuine HP 826A four-color toner set and HP 828A four-color drum set. Each covers black, cyan, magenta, and yellow for its own supply type, so choose toner or drums according to the component your printer needs.
