[Samba] Cups problem

[morgan31 at libero.it]

Hi list,
I've got some problems with my Windows Printer (Hp deskjet on Windows
2000 server via LPT1).
I've configured the printer as shared, the name is hp.
On my linux box I've installed samba 2.2.3a and the configuration is ok
for the disk shares.
My [printers] section is :
[printers]
        comment = All Printers
        path = /var/tmp
        create mask = 0600
        printable = Yes
        browseable = No
        print command = lpr-cups -P %p -o raw %s
        lpq command = lpstat -o %p
        lprm command = cancel %p-%j

I've added a valid user "morgan" in the smbpasswd file.
When I try to print the error always is:
lpr:unable to print file:server-error-non-accepting-jobs

What does it means?
All machines in my network can use it for printing.
Any suggestions?
Thanks
