What should I do if I cannot print on my Windows computer?

First, check for error messages and resolve them. Then ensure your HP Photosmart is set as the default printer and is not offline by checking Devices and Printers (Windows 7), Printers (Windows Vista), or Control Panel/Printers and Faxes (Windows XP). Look for a check mark in a circle next to your printer. If the printer software installation failed, remove the CD, disconnect the printer, restart your computer, disable any firewall/anti-virus temporarily, insert the CD again, and follow the onscreen instructions.
