The HP DesignJet Z9+ 24-in PostScript Printer (W3Z71A) is the photo-grade member of the DesignJet Z lineup at 24 inches wide — 9 pigment inks (cyan, magenta, yellow, photo black, matte black, chromatic red, chromatic green, chromatic blue, gray; gloss enhancer optional), 5 universal printheads with 21,120 nozzles total, and an embedded i1 spectrophotometer from X-Rite for closed-loop calibration. Print speeds run 55.7 m²/hr fast on plain media (13.4 m²/hr normal on coated, 3.5 m²/hr best on glossy). Resolution is up to 2400 x 1200 optimized dpi with HP Pixel Control for smooth gradients. The thing photo buyers love: short-term color stability under 1 dE2000 in 5 minutes, so you can ship a print without a 24-hour color settle. Native PostScript 3 + PDF 1.7 + TIFF/JPEG/CALS G4/HP-GL/2/HP-RTL covers Adobe and CAD workflows without a third-party RIP. HP Secure Boot, whitelisting, and a 500 GB self-encrypting HDD cover compliance work. Buyers regret: paying for the Z9+ when their work is mostly CAD and maps (Z6 is the right answer for non-photo). Footprint is 50.9 in wide; weight 159-216 lb. Comes with printheads, intro 746/747 cartridges, stand, media bin, spindle. 3-in core adapter is not included on 24-in models — add CN538A if you need it.
