are you running vista? if so try the driver for Photosmart 7200
To install the driver use the following steps:
Click the ‘Start’ Icon, and select ‘Control Panel’ in the start menu.
Once the Control Panel window opens, double-click the ‘Printers’ icon.
In the ‘Printers’ window, click the ‘Add a printer’ icon/link in the top menu bar.
In the ‘Add Printer’ dialog window, select ‘Local Printer’ and ‘Next’.
When asked to ‘Choose a Printer Port’, select ‘Use an existing port’ and click on the ‘USB001 (virtual printer port for USB)’ item in the list. Then click Next.
On the following page, select ‘HP’ or ‘Hewlett Packard’ in the left pane, and find ‘Photosmart 7200′ in the list on the right.
IMPORTANT: Plug in the Printer now, if it’s not already plugged in, and switch it on.
Click ‘next’ and then print a test page
