HP Smart Print is HP's new Web page printing software, supported in 32-bit Internet Explorer (IE) versions 6 through 9.
HP Smart Print replaces HP Smart Web Printing Software, which was only supported in 32-bit IE versions 6 through 8. If you try to run HP Smart Web Printing in 32-bit IE 9, the program will not open, and an error message might display on the computer.
note:HP Smart Web Printing is no longer available for download.
How do I know if my IE browser is 32-bit or 64-bit?
In your Internet Explorer browser, click Help, and then click About Internet Explorer. If the version is Internet Explorer only, you have the 32-bit version. If the version is Internet Exploer 64-bit version, you have the 64-bit version.
