Jobs added from Samba unloaded without printing

I installed a Samsung CLP-300 Printer on a Debian machine.

I have 2 problems:

1. I added the Samsung printer using the CUPS admin web page. When I try to print, I get this message: "Printer not connected; will retry in 30 seconds...".
The only workaround I found for this error is changing the Device URI from usb://Samsung/CLP-300 to file:/dev/usb/lp0.
Using the file:/dev/usb/lp0 URI I'm able to print.
Do anyone has any idea why the usb://Samsung/CLP-300 URI doesn't work? Is it a problem using file:/dev/usb/lp0 URI?

2. I've a problem printing from Windows XP using Samba. Looking inside the CUPS error_log, I found that Samba actually sends a new job to CUPS, unfortunately this job is immediately unloaded and no printing is performed.
I compared the error_log of a job added from an application running on the same machine with the log of a job added from Samba. I guess the problem could be the different content types of the two jobs: the samba job (not working) specifies "application/vnd.cups-raw" content type, while the working job has "application/postscript" content type.

Here is the error_log of the job added from Samba (not working):
