How do you disable SMB printing support?

Solution 1:

Commenting out the printers section actually does nothing, add this to your smb.conf:

load printers = no
printing = bsd
printcap name = /dev/null
disable spoolss = yes

(spoolss is not a typo)

Solution 2:

Becareful about missing network interfaces referenced in Samba config file! Put: log level = 2 into cinfig file, restart Samba and check log entries. Worked for me ;-)
