Commenting on the results, HP chairman and chief executive Mark Hurd said the company was now "well-positioned to outperform the market".
The manufacturer recorded group-wide sales of $31.2bn for the quarter ending 31 January 2010, helped in part by a 9% revenue increase in the Americas and a 1% increase in Europe.
Within IPG, commercial hardware revenue rose 4% while shipment of hardware units was up 11%. Operating profit came in at $1.1bn.
"The strength of our portfolio, leaner cost structure and accelerating market momentum give us the confidence to raise our full-year outlook," Hurd added.
For the second quarter of 2010, the company anticipates revenues of between $29.4bn to $29.7bn and a full-year showing of between $121.5bn and $122.5bn.
HP's share price rose to $50.79, up from $49.44 on 16 February, prior to the results announcement.
