    i can print test page in the redhat, but when i use the samba shared
printer to print test page,

it is said "test page failed to print"  why?


one part of my smb.conf as follow:


        printcap name = CUPS
        load printers = yes
        disable spoolss = no
        show add printer wizard = yes
        printer admin = samhuang,GZ+samhuang
        printing = cups


any help would be appreciate
