I see a lot of posts in this section, but not everyone is reading the previous posts.
If you have an HP F300 series printer, the Snow Leopard OS X 10.6 drivers are not yet available for download.
What you should do, while your waiting for the new print drivers, is go to the HP web site and download the printer driver that is specific to the HP F300 series of printers. The lastest Mac OS X HP F300 printer driver version is for Leopard 10.5. Download this print driver and install it. You will then be able to print to your F300 series printer with no problem. However, the HP F300 scanner software will not work with Snow Leopard. This is not a problem because if you wish to scan, you can use the Snow Leopard scan driver which is automatically installed when you installed Snow Leopard.
To use the scanner, go to your Preferences, and select Printers. Click on the Scan option and you'll enter the scanning interface (note, I'm doing this part from memory at the moment as I'm on my PC laptop so hopefully I didn't leave out a step).
The bottom line is that the HP F300 printer driver for Leopard 10.5 works fine with Snow Leopard 10.6. When the Snow Leopard HP F300 print driver becomes available, it will automatically update the previous driver.
Hope this has been of help.
