Kodak then began a strategy shift: while Kodak had previously done everything in-house, CEO Antonio Pérez shut down film factories and eliminated 27,000 jobs as it outsourced its manufacturing. Pérez invested heavily in digital technologies and new services that capitalized on its technology innovation to boost profit margins. He also spent hundreds of millions of dollars to build up a high-margin printer ink business to replace falling film sales. Kodak's ink strategy rejected the razor and blades business model used by dominant market leader Hewlett-Packard in that Kodak's printers were expensive but the ink was cheaper. As of 2011, these new lines of inkjet printers were said to be on verge of turning a profit, although some analysts were skeptical as printouts had been replaced gradually by electronic copies on computers, tablets, and smartphones. Home photograph printers, high-speed commercial inkjet presses, workflow software, and packaging were viewed as the company's new core businesses, with sales from those four businesses projected to double to nearly $2 billion in revenue in 2013 and account for 25% of all sales. However, while Kodak named home printers as a core business as late as August 2012, at the end of September declining sales forced Kodak to announce an exit from the consumer inkjet market.
