That's partly because the Fuji, Kodak and Olympus all came remarkably close to true continuous-tone output. The Fuji's photos were so close, the lab found fault more with the digital image than the printer. A dot pattern did show on printouts from the three ink-jet printers, although it took a discriminating eye and close inspection to see it on the Epson. Considering their low cost, the ink-jets really delivered. The Ko dak gave good quality and versatility through PostScript Level 2 and an Ethernet card.
Slowness is a different issue.
But not one printer took less than a minute per photo to print sample images. All averaged 3 to 5 minutes per photo. Speed concerns aside, buyers of photo-quality printers primarily want quality, so that is the focus of this review. Some were scanned photos, others were digital artwork. All had different composition and format.
