SAN FRANCISCO (06/23/2000) - Lexmark International Inc.'s lively new Z52 Color Jetprinter supplants the Z51 at the top, earning a Best Buy thanks to its speedy text, strong print quality, and reasonable $179 price. Hewlett-Packard Co.'s new DeskJet 842C leaps onto the chart at number six. At a low $149, the DeskJet 842C turns in slower speeds than other HP models, but produces good output. Meanwhile, new inexpensive printers from Epson America Inc. and Canon Inc. didn't quite cut the mustard.
