Thank you again Louis !

I have tried with the standard Espon drivers but the printing is still
very buggy. I can't understand if the problem come from, the windows
client, the samba server or the cups server. I have some questions :

1) When you push the driver to samba. You need to first install the
driver on one client. During the install the driver query the printer
port to configure the printer on the client. At this stage I set
voluntary a non existing port like "parallel1" because I think that I
only need to push the driver files. I'am right ? Or did I need to
correctly configure the client to use the samba port when installing
the driver to the first client ?

2) My CUPS server is not used only by Samba. I have many Linux
clients. So I have not set the CUPS printer's drivers to "RAW" but
with the correct PPD drivers (PS3 or Foomatic/PostScipt). The printers
work from the linux client. Is this a problem for Samba to set the
driver in CUPS ?

3) When you send print jobs from your Windows clients by Samba->Cups.
Is the jobs appearing on the CUPS web page ? When you query "ended
jobs" ?

Thank you very much !

Baptiste.
