Running samba v3.3.9 on debian lenny to serve 300 printers to windows clients (point and print). Drivers are installed on the server using APW from windows client. After upgrade to v3.5.2 the 'Printing Defaults' button dissapear from all the queues:
If I upload a new driver to the server and apply and close the window then the "Printer Defaults" button shows again:
However, this button will eventually disappear after opening/closing the driver properties window a few times.
If I downgrade to v3.3.12 then the problem fixed. This problem is reproducible.
This sounds similar to my printer problems remaining in Bug ID #6727 after GD made a patch that got included in 3.5.2.
I don't this this bug exists any more, please reopen if this is still reproducible with 4.7 or later.
