Hi,
I solved some issues with printers on Zentyal by editing the /etc/samba/printers.conf and changing the line
show add printer wizard = no
to
show add printer wizard = yes
then restarting samba.
Via the "Print Management" MMC add-in I can now deploy via GPO and start the Add Driver dialog, but... I still have issues with adding the printer drivers - it just wont run. I get a message saying that I can't install the driver as it's not a valid 64 bit driver for the hardware device (they are 64 bit when installed using the supplied setup programs).
My printers are from varying makes - HP, Kyocera, Xerox, Ricoh, Canon - but none of them install.
Would be nice to be able to just copy the required files to the $print directory and be done with it!
EDIT: Some branches in the forest in the GPO deploy dialog screens don't work - you have to keep trying until you find the printer... somehow...
