Cannot print with a windows 7 connected printer

Question

Mac Book Pro 13'' Mac OS 10.6.4, windows 7 hosting a Deskjet F370 (F300 series) and there is NO WAY i can print from the mac to the windws connected printer.
1- Printing sharing enabled,
2- LPD & LPR protocols enabled,
3- homegroup disabled,
4- file sharing works via SMB like a charm,
5- password protected sharing disabled.
I think i'm not forgetting anything. When I try to add the printer in my mac -
Sys pref > Print&fax > add > advanced > method 1: LPD/LPR > lpd://IP/ShareName
method 2: Windows > smb:// > I always select the driver F300 from the list (no gutenprint available). Finally the printer is added to the list after a long wait, but it doesn't work in any way. Please......help, thanks!

Hi
I install the three packages in the website you provided and tried again with the new driver, i still cannot print.
Somehow i found two print jobs in the Window's queue, couldn't print them, i thought they belonged to the new driver session, but since i coulnd't get to add new jobs in the queue again i don't know anymore, In the mac i've tried it as a registered user and guest, no difference, it asks for password, i provided it and it keeps waiting for authentication (On hold, authentication required), i even removed the password from my administrator account in windows and nothing.
if i go to job info in the mac it tells me among other things:
Status: On Hold (Authentication required)
Job message: Session setup failed: NTSTATUS_INVALIDPARAMETER
Don't know what to do.
