Just a quick note to say that if you are having issues with printing after upgrading to Mac OS X 10.6.7, generally to Windows printers, there is a slight problem with permissions on a file in the printing system.

This can be fixed by logging in as an Admin on the system, going to a Terminal window (in “Applications – Utilities”), and running the following command:

sudo chmod 0500 /usr/libexec/cups/backend/smb

You’ll be prompted for your password.  Type the password and push enter – and the problem should go.

Note that some people might use the “Disk Utility” feature called  ”Repairing Permissions”.  However this doesn’t fix this problem, and in fact may change the permissions to another setting so keep an eye out.
