Since this story was originally posted, it has been corrected to clarify the printer features described in the final paragraph.Hewlett-Packard (HP) is upgrading its inkjet printers to appeal to small business owners for whom a big business machine is too expensive but a small consumer-oriented printer inadequate.Meanwhile, HP faces new competition in the consumer printer market from Eastman Kodak, which introduced new inkjet printers Monday.HP on Tuesday launched the HP Officejet J5700 printer series, scheduled to go on sale this month at a starting list price of US$149. Also coming on the market, in March, is the Officejet Pro K5400 series, starting at $149, and the Officejet Pro L7000, starting at $299. Each of the new printers\u00a0is identified as "All-In-One," which means they can print, scan, copy and fax documents.HP is migrating down to the sub-$300 market features previously available in more expensive laser printers used by businesses and large enterprises, said Karl Schwenkmeyer, vice president of marketing for inkjet systems within HP\u2019s Imaging and Printing Group.HP seeks to dispel some misconceptions about how inkjet printers can\u2019t handle business workloads because they are too slow, expensive to maintain and unreliable, Schwenkmeyer said. He said the printers can print color pages for as low as $0.06 each and black ink documents at as low as $0.015 each. And the machines are engineered to print 7,500 pages a month without a failure.Offering new features in lower-priced printers is a lot like carmakers that first put antilock brakes only in luxury cars but now also offer them in compacts, said Robert Palmer, director of printer research at InfoTrend, a printing market research firm."There\u2019s nothing here that is really new, but they [HP] have done a good job of putting products out that are more robust," said Palmer.HP holds a market share lead of 50 percent in the inkjet printer market, according to 2005 InfoTrend numbers, said Palmer. Lexmark International follows with 16 percent, while Dell has 15 percent. Seiko Epson has 12 percent and Canon 8 percent. But one more company is lining up to challenge HP.Kodak entered the consumer inkjet market on Tuesday with models that aim for the heart of HP\u2019s printing profitability: the replacement ink cartridges. Kodak\u2019s replacement cartridges list for $9.99 for black ink and $14.99 for five-color ink, about half what HP and other brands charge.Different models of the Kodak machines, which can print, scan and copy\u2014but not fax\u2014documents, list for $149.99 and $199.99. One higher-end model, which lists for $299.99, can fax documents. They are also targeted at consumers and home-based business operators.-Robert Mullins, IDG News Service (San Francisco Bureau)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
