Hint: cupsomatic seems to fail for me when getting a PDF job from my mac. Changing debug to "1" (my debug="1") in cupsomatic helps.
To enable printing from Jaguar via Samba to Windows machines, you've got to include "smbspool" as cups backend. Grab Terminal as root and enter:
% cd /usr/libexec/cups/backendNow reboot (or restart cups by "kill -HUP"). Print Center cowardly refuses to add SMB printers. So grab your favorite browser and enter "http://127.0.0.1:631" as URL. Go to printers, add a printer, and use "Windows Printer via SAMBA" as Device. The printer URL may be one of the following, depending on your environment (see cups documentation):
% ln -s /usr/bin/smbspool smb
smb://user:pass@workgroup/server/sharenameUnfortunately, the number of printer drivers included with cups is quite low and the usual MacOS X vendor drivers are not updated yet. If you don't find your model listed, consider gimp-print. You need the Developer Tools to compile and install gimp-print.
