Well, I've been waiting for something like this for months now... What I 
must admit is that : First, I still have not understood all about CUPS 
backends, and moreover, I haven't got any printer with "strange" drivers 
so I cannot test JASmine-Backend in these situations. By "strange" 
drivers, I mean cheap printers that are not Postscript/PCL ;-), because 
at work all our printers are laser or business jet.

So, here is the problem : CUPS' behaviour is different in raw mode and 
'normal' mode. I know that in one of these modes, the "copies" parameter 
sent to the backend must be ignored, as the document already contains the 
copies. And when operating in the other mode, the backend _must_ take 
care of the copies itself...

I haven't worked on this issue for now, and I'm not sure that JASmine 
should do copies, because it's and intermediary backend. Well, in fact 
i've got a small idea : JASmine should launch the final backend the same 
way it was itself launched, using the same number of arguments. It 
doesn't at the moment, and always uses the same mode.

Jerome, what are your thoughts about it ? How do you do this in Pykota ?
