The driver for your HP product is already included in the Windows Vista operating system. You do not need to download a driver to use the product.

Check out this page to learn how to install the in-Operating System driver (in-OS driver) included in Windows Vista with your HP printer.

Did you check the Microsoft Compatability Listing for the model 630 printer? There may not be a driver for your Vista 64 OS. Search Microsoft Compatability List using your favorite search engine to find the list.

If your printer is listed, great. If not, you will have to go to www.hp.com/support to find a driver. If none is offered there, you can always ask HP. HP responds to public inquiry for drivers if there is enough interest shown. Failing that, you might find 3rd party drivers that may work to your satisfaction. ... and alas, lastly, if you can't find a driver, your alternatives are limited to: Running your printer on a compatable computer/OS, using that computer as a print server on your network or ... purchasing a new printer.

here u can download driver..

Hi:
I can get the printer supported by using the Epson Stylus C45 Series (M) printer driver.
Works fine, but scanner does not.

1. Turn the printer off and open the cover.
2. Lift the right black rectangular paper sensor (located in the middle of the printer just below cartridge slides) clean it up, try with vacum cleaner first if it does not help use coton swabs and clean it.

Good luck

From what I can see Vista already has the drivers for this printer built in, so if you have installed the Windows XP drivers from CD you may need to remove them first and see how it goes with the standard Vista drivers.

Please note that some functions may not be available as this product is not completely Vista compatible.
