The streamlining announced Wednesday represents HP’s largest payroll purge in its 73-year history. The reductions will affect about 8 percent of HP’s nearly 350,000 employees by the time the overhaul is completed in October 2014.

The cuts come eight months after HP hired Meg Whitman as CEO to turn the company around.

HP hopes to avoid as many layoffs as possible by offering early retirement packages.

The company expects to save $3 billion to $3.5 billion annually from the job cuts and other austerity measures.

“While I wouldn’t say we have turned the corner, we are making real progress,” Whitman told analysts during a conference call.

Echoing comments she made three months ago, Whitman cautioned that “turning HP around is going to be a lot of hard work. It’s going to take time. But we know what needs to be done.”

Investors were pleased, although it wasn’t clear whether their glee had more to do with the cost-cutting or the company’s performance during its fiscal second quarter, which ended in April.
