running xubuntu 12.10 on both linux samba server and linux client

linux client machine cannot connect to samba printer served via linux server

have usb printer on linux machine serving via samba

testparm shows this:
comment = All Printers
path = /var/spool/samba
create mask = 0700
printable = Yes
print ok = Yes
browseable = No

comment = Printer Drivers
path = /var/lib/samba/printers


smbtree shows:

\\CWX4A cwx4a server (Samba, Ubuntu)
\\CWX4A\HP-LaserJet-5M Hewlett-Packard HP LaserJet 5M

a window's machine can print via samba to \\CWX4A\HP-LaserJet-5M

when adding a printer from a Linux Client and browsing then for the LaserJet 5M
it sees it but no matter what user name and pasword I give it fails to allow connection

says "Print Share Inaccessible"

somebody got an answer to resolve this?
