The Personal Systems segment, which includes HP's PC business, posted revenue of $10.2 billion, up 13% year-over-year, with commercial PC revenue rising 14% and consumer PC revenue rising 10%, the company said. Despite the strong revenue performance, overall PC unit volumes declined 7%, a divergence pointing to higher average selling prices as the primary driver of growth rather than any expansion in units sold. The Printing segment reported revenue of $4.2 billion, flat year-over-year, with an operating margin of 18.3%, down from 19.2% a year earlier.
