As part of its bankruptcy reorganization, Eastman Kodak is planning to wind down sales of consumer inkjet printers next year, products that were once called a crucial part of its turnaround effort.

The company’s announcement, which was made on Friday, said Kodak would focus instead on selling packaging, printing and other services to businesses. Kodak will continue to sell ink for consumer printers and said it expected to “significantly improve cash flow” in the United States in the first half of 2013.

“Kodak is making good progress toward emergence from Chapter 11, taking significant actions to reorganize our core ongoing businesses, reduce costs, sell assets and streamline our organizational structure,” Antonio M. Perez, the company’s chairman and chief executive, said in a statement.

A former Hewlett-Packard executive who joined Kodak in 2003, Mr. Perez had focused on consumer inkjet printers as a cornerstone for Kodak’s turnaround, despite significant skepticism from Wall Street analysts. But the Jan. 19 bankruptcy filing forced major changes at Kodak.

In February, for instance, Kodak announced that it was getting out of the digital camera business, and in May it closed the sale of its online photo-sharing business, Kodak Gallery. In August, Kodak announced that it was also selling its consumer film business, featuring the familiar yellow boxes that made the company a household name.

The company, which is based in Rochester, N.Y., expects to reduce its work force by 3,900 jobs this year, a 23 percent reduction
